[Interpreted] Hello, everyone, and thank you for joining our call today. 2025 was a pivotal year for EHang as we strengthened our business foundation and made a meaningful progress towards commercialization. In Q4, we delivered a strong set of results. Quarterly eVTOL sales volume reached 100 units for the first time. Revenues grew significantly both year-over-year and sequentially, and we achieved our first ever quarterly GAAP profitability. For the full year, we delivered 221 units of eVTOL aircraft, setting a new record and successfully meeting our annual revenue guidance. We also achieved non-GAAP profitability for the second consecutive year. These results reflect years of sustained investment and disciplined execution across product innovation, regulatory certification, industrial ecosystem development and market expansion, laying a solid foundation for our commercialization progress in 2026. I am pleased to announce that the commercial operation of our flagship product, the EH216-S is entering the final count down. Following comprehensive preparation across our commercial operation system, we're about to officially open our commercial flight services to the public. After nearly a year of internal trial operations, we have established standardized procedures across the entire operational chain from route planning and fleet management to boarding services. At the same time, we have optimized our maintenance systems and safety assurance mechanisms while actively supporting the Civil Aviation Administration of China in advancing the training and certification program for our ground operating crew. Our 2 OC certified operators, EHang General Aviation and Heyi Aviation both plan to begin offering ticketed EH216-S flight services to the public this month and their operational sites in EHang Future City, our new headquarters in Guangzhou and Luogang Park in Hefei. This launch is expected to mark the world's first commercial service of pilotless human-carrying eVTOL aircraft. It also represents the completion of EHang's full life cycle ecosystem from technology development and airworthiness certification to manufacturing and commercial operations. Going forward, we are evolving from being an aircraft manufacturing to a comprehensive provider of integrated advanced air mobility solutions. 2026 marks the first year of China's 15th 5-year plan period. As the national strategic emerging pillar industry, the low altitude economy is embracing unprecedented strategic development opportunities. Supportive policy direction is now shifting from encouraging exploration to systematic advancement with the continued progress in aerospace management reform, airworthiness notification frameworks and infrastructure development. Together, these initiatives are creating a favorable policy environment for industry development. With that in mind, EHang's core strategy for this year are to move forward with a disciplined execution, strengthening our foundation while steadily advancing commercialization, operational ecosystem development and global expansion. First, it has been nearly a year since EHang obtained OC for EH216-S. Over the past year, we have been working intensively to expand our customer and partner base. At the same time, we built the operational systems required to support the commercial flights. This year, our top priority is to launch routine and scaled commercial operations of human-carrying eVTOL aircraft to the public, delivering reliable flight services and continuously improving the flight experience. Our goal is to transform scenes in science fiction into everyday reality for people. This is a milestone many people have been waiting for and so have we. But aviation has always been an industry that moves forward with patience and responsibility, especially when safety and human lives are involved. Second, we'll continue advancing our global expansion strategy. Taking the Thailand AAM Sandbox initiative as an example, we are steadily moving towards a commercial flight operations and established benchmark projects. I'm also pleased to share good news that EHang is expected to obtain the first commercial operation license for pilotless passenger eVTOL aircraft from the Civil Aviation Authority of Thailand, paving the way for regular urban air mobility services in the country. Third, we'll accelerate the commercialization readiness of the VT35. In 2026, our focus will be on advancing its time certification and conducting extensive flight test in more diverse and complex environments to fully validate its passenger flight capabilities. At the same time, we'll continue improving the performance of the EH216 series and expanding the deployment of nonpassenger products and applications, including firefighting and logistics, further broadening our market reach. Fourth, we'll further strengthen our end-to-end industrial chain integration capabilities by coordinating our R&D, manufacturing, supply chain and quality management systems. We aim to improve operational efficiency across the entire value chain, reinforce our long-term competitive advantages and contribute to the establishment of industry standards. EHang remains committed to the principles of safety first innovation-driven growth and collaborative development. We will continue advancing our technology and product innovation, expanding multi-scenario commercial operations and establishing AAM operational models in more regions around the world. At the same time, we're building a comprehensive business model combining technology, R&D, intelligent manufacturing, commercial operation services, infrastructure collaboration and industry education and integration. We believe the low altitude economy industry will evolve from demonstration programs to scale commercial operations and then to public accessible services. It will become a vital engine for activating 3 dimensional aerospace resources and cultivating new forms of consumption, truly transforming the industrial values into economic and social benefits. At this important starting point of a pivotal year, our newly appointed Chief Technology Officer, Feng Shuai, is also joining today's earnings call. Under my leadership, he will oversee our technology R&D, supply chain management, manufacturing and quality system development, driving a more integrated end-to-end management approach from technology innovation to product delivery. By strengthening coordination and the integration across the entire industry chain, we believe our innovation capability, product competitiveness and overall execution will continue to improve. With that, I would like to hand the call over to Feng Shuai. Thank you.

[Interpreted] Thank you, Mr. Hu. Hello, everyone. I'm Feng Shuai, CTO of EHang. It is a great honor to join today's earnings call for the first time. I am pleased to share our progress in 4 key areas during the fourth quarter. R&D, production and manufacturing, quality management and supply chain assurance, which we refer to as the RPQS Center. We'll also briefly outline our priorities for 2026. The RPQS Center is the core engine of our technology and industrial execution. We focus on technology innovation as the foundation, production capacity as the driver, quality control as the bottom line and supply chain as the cornerstone. Together, these capabilities support the development, commercialization and scale delivery of our products. Let me walk through the key highlights in each area. Starting with R&D. The fourth quarter of 2025 marked a major breakthroughs across our core product. Our flagship passenger carrying aircraft, VT35 completed multiple critical tests, including multicopter protected transition flights and locked-to-prop fixed wing flights. The aircraft also successfully completed its first public demonstration flight in Hefei after its grand debut in October. During the quarter, we held the first type certification team meeting with the CAAC, marking a key step forward in the airworthiness certification progress. We are currently conducting flight envelope testing and aim to obtain the type certification in China within the next 2 years. For the nonpassenger business, we are also developing and deploying product and system lines under multiple application scenarios. Our new GD4.0 formation drones set a Guinness World Record with 22,580 units flying simultaneously at the China Spring Festival Gala, significantly announcing our brand visibility and generating strong demand for both drone products and performance services. In the firefighting aircraft program, we are upgrading the current models while advancing the next-generation R&D to support emergency response scenarios. For logistics, we are accelerating the development and first flight of the VT series lift and cruise cargo aircraft, developing longer endurance aerial logistics applications. At the same time, our proprietary command and control system continues to evolve as a city-level digital infrastructure platform for a low attitude economy is now being trial operations in Hefei, providing solid tech support for future skilled commercial operations and air traffic management. On manufacturing, we continue to expand our production capability and enhance the smart manufacturing capabilities during the fourth quarter. The Phase II expansion of our Yunfu production facility was successfully completed, bring our total plan annual capacity to 1,000 units of the eVTOL aircraft and components. The automated production lines have entered a trial product to stage and our smart manufacturing systems will further improve production efficiency and supply chain management. Meanwhile, additional facilities in Hefei, Weihai and Beijing are progressing as planned. Our nationwide manufacturing footprint is steadily taking shape. We follow a manufacturing to order approach, ensuring stable production planning while preparing large-scale deliveries in the future. On quality control, we maintain strict end-to-end quality control across the entire product life cycle. Throughout 2025, our quality management system delivered strong performance with steady improvements across all key indicators. The post-certification airworthiness review for our [ PC ] achieved the third zero defect pass and the EN9100 audit continues to pass. On supply chain, during the fourth quarter, we further expanded our supplier network and strengthened our supply chain resilience. Our core supplier system remained stable with a 100% on-time delivery rate for key components, fully supporting our production and deliveries. Going forward, we will continue our strategy of maintaining strong partnerships while introducing additional high-quality suppliers. This approach will strengthen our stable and scalable supply chain, providing support for future capacity expansion and new model development. The low attitude economy represents a new frontier for technological industrial innovation, strong R&D and smarter manufacturing capabilities are the foundation of our long-term competitiveness. As CTO, I'll continue leading the RPQS team to drive technology innovation, advance product development and certification, expand manufacturing capacity and smart production capabilities, maintain strict quality standards and strengthen supply chain resilience. Our goal is to efficiently translate technological innovation into real commercial deployment and provide a solid technical and industrial support for the company's long-term growth. With that, I'd like to turn the call over to our COO, Mr. Wang Zhao, for our sales and operations update in more detail. Thank you.

[Interpreted] Thank you, Mr. Hu and Mr. Feng. In 2025, we advanced our business across 3 key priorities: safety, operations and commercialization. For the full year, we generated RMB 509 million in revenues and delivered 221 units of eVTOL aircraft, including 215 units of EH216 series and 6 units of VT35 series. Our Q4 performance reached a new high. We delivered 95 units of EH216 series and 5 units of VT35 series, generating RMB 240 million in revenues. In China, we continue to deepen our presence in key cities and build flagship partnerships. In Hefei, our collaboration with the local government expanded from a single product to a full product portfolio. The corporation now covers multiple applications, including the EH216 series human-carrying and firefighting versions, the 5 VT35 the GD4.0 formation drone. We also continue to strengthen our partnership with Anshun in Guizhou Province and Guizhou Tourism Group. In Q4, 30 units of EH216-S were delivered to the local market, bringing total deliveries to 50 units to this customer, supporting the development of a local low attitude economy applications. Building operational capability has been a major strategic focus throughout the year after EHang General Aviation and Heyi Aviation obtained their operator certificate in March 2025, we began to conduct extensive internal testing and operational optimization across the entire service process, from ticket booking and on-site verification to boarding and flight operations to ensure a seamless user experience. At the same time, we have established a comprehensive set of standard operating procedures covering battery charging, maintenance and fault troubleshooting to ensure the continued airworthiness and operational stability of the fleet. Based on the safety and operational experience we have accumulated, we plan to officially launch commercial operations with the EH216-S in this month. EHang General Aviation and Heyi Aviation will begin selling flight tickets to the public offering EH216-S pilotless aerial sightseeing our headquarters in Guangzhou and Luogang Park in Hefei. The public will be able to book flights through the EHang Trip and the Heyi Aviation mini programs with an early bird discount price of RMB 299 per person. This will be the world's first ticketed commercial service for pilotless human-carrying eVTOL in the urban air mobility industry, transforming the low altitude economy from a concept into a reality that is accessible to the general public. Over the past year, we have carefully refined every aspect of the operation. Our approach has always been safety first, experience-focused and sustainability driven. Delivering a high-quality flight experience for our passengers in the initial phase is crucial to building public trust and supporting long-term market adoption. Looking ahead, we will leverage the experience from our OC certification and operations to develop a comprehensive operational solution covering [indiscernible], planning, routes design, ground crew team training and operational system set up. We plan to replicate this model across more locations in China and overseas to support our customers and partners in launching commercial operations. It is worth noting that we are building a core note for our operational capabilities, a professional talent system. We're actively working with the CAAC on the trial project for the administration of licenses for the ground operating crew of large civil unmanned aerial vehicles. We have completed multiple rounds of validation and refinement of training courses. Recently, the CAAC has expanded the number of special approval license to ground operating crew for us, providing additional talent support for our upcoming commercial operations. Beyond meeting immediate operational needs, this initiative is helping establish a long-term industry talent training system. Together with the regulator, we are converting our front-line operational experience into standardized training procedures. This helps establish professional standards for a new generation of aviation talent and strengthens the safety foundation of the industry. Over time, this training framework will enable us to support partners and export our operational capabilities as commercial operation expands. On the international front, the Thailand AAM Sandbox program remains our key focus. Since its launch in October last year, we have completed a series of verification flights and ongoing trial operations. We are now working closely with the Civil Aviation Authority of Thailand to obtain the first commercial operation license under the Sandbox initiative. If approved, this could become the first overseas commercial operation of a pilotless human-carrying eVTOL. The initial Sandbox areas are planned near the IMPACT Challenger International Convention Center in Bangkok, which will also host the ICAO Second Advanced Air Mobility Symposium or AAM 2026. The CAAT and local partners have set a clear goal of operating up to 100 eVTOL aircraft across 20 Sandbox areas by the end of 2026. Our plan is to establish talent as a model for overseas operations and gradually replicate this model in South East Asia and other [ belt and road ] market. Overall, in 2025, we maintained a disciplined approach to growth, focusing on strengthening our product, manufacturing and operational systems under a strict framework of safety and regulatory compliance. We believe that building these foundational capabilities is essential to support sustainable growth and scalable international expansion in the years ahead. At the same time, the low altitude economy industry is entering an important policy window. China's 15th 5-year plan has elevated the low altitude economy to a level of strategic emerging pillar industry. This signals the transition from early demonstration programs to a new phase of national level industry development. The low altitude economy has also been formally incorporated to the newly amended civil aviation law of China, which took effect in 2026. Looking ahead to 2026, we believe the company is entering a new stage of development. Over the past several years, we have been systematically building the key capabilities required for the urban air mobility industry, including aircraft R&D, airworthiness certifications, smart manufacturing and commercial operation readiness. As these foundational capabilities continue to mature and integrate, we see 3 important shifts in our business model. First, our revenue streams will gradually become more diversified. Applications beyond a passenger transportation, including logistics, aerial firefighting solutions and commanding control systems are progressing steadily and could become additional growth drivers as the market evolves. Second, we're evolving from an aircraft provider to a one-stop low attitude operation solution provider, leveraging the operational experience of the EHang General Aviation and Heyi Aviation, along with our standardized operating systems, and we will offer integrated solutions to customers. These include aircraft deliveries, [ vertical ] construction, route planning, team build up and training and operational guidance. Third, we're establishing a clear pathway for overseas expansion that combines regulatory Sandbox programs, partnerships with local operators and systematic deployment of our technology and operational capabilities. Thailand is the first to market where this model is taking shape, and we expect to gradually expand to other regions, including Southeast Asia, Central Asia and the Middle East as global regulatory framework continue to evolve. Overall, we remain committed to a strategy of safety first and disciplined execution. For 2026, we are targeting RMB 600 million of annual revenues while continuing to scale the business at a more steady pace. As the industry is still in its early stages, we'll continue to work closely with regulators, partners and local governments to help move the low altitude economy from demonstration programs to a broader commercial adoption, unlocking the long-term potential of urban air mobility as the new form of transportation. Now I'll turn it over to our CFO, Conor, to walk us through the financial results.

[Interpreted] Hello, everyone. Before I go into the details, please note that all numbers presented are in RMB unless otherwise stated. A detailed analysis is available in our earnings press release on the IR site. Now I will present some key financial data. In Q4 2025, the revenues were RMB 243.8 million, up 48.4% year-over-year and 163.6% sequentially. The quarterly increase was primarily driven by higher sales volume of our products, including 95 units of the EH216 series and 5 units of VT35 delivered this quarter. For the full year, the total eVTOL deliveries reached 221 units and revenues totaled RMB 509.5 million, representing 11.7% increase year-over-year, surpassing our annual guidance. This growth reflects the sustained market demand for our products as well as our effective execution and delivery management, customer support and commercial operation readiness. Gross margin in Q4 was 62.1%, improving from 60.7% in Q4 of 2024 and 60.8% in Q3 of 2025. For the full year of 2025, gross margin was 62%, improving from 61.4% in 2024. As production scale expanded, overall cost efficiency continued to improve. Overall, the company maintained a gross margin above 60%, reflecting our strong product competitiveness, scaling production capability and display cost management in the eVTOL sector. Turning to operating expenses. In Q4, adjusted operating expenses, defined as operating expenses excluding share-based compensation, were RMB 99.3 million, representing a 26% year-over-year increase from RMB 78.8 million in Q4 2024 and an 11.4% increase from RMB 89.1 million in Q3 2025. For 2025, adjusted operating expenses were RMB 348.9 million, representing a 20% increase from [ RMB 290.1 million ] in 2024. The increase in operating expenses was primarily driven by the continued R&D innovation, expansion of our product sales and the company's commercialization efforts. As we scale our business, we have strategically expanded our sales network, strengthen our operations team and added a key R&D talent, while maintaining ongoing investments in the development and iteration of new eVTOL models like VT35 and EH216-F series and et cetera, and related technologies to enrich our product pipeline and lay the groundwork for future revenue streams. As the company's revenue continues to grow with operating expenses increasing modestly, operating efficiency has been steadily improving, particularly in the fourth quarter where overall profitability saw a significant improvement. In the fourth quarter, we achieved our first quarter of GAAP profitability with net income reaching RMB 10.5 million. Adjusted operating income for the fourth quarter reached RMB 54.3 million, representing a year-over-year increase of 99.5% and a substantial sequential turnaround from a loss. Adjusted net income for the fourth quarter was RMB 71.5 million, up 96.4% year-over-year, also achieving a sequential return to profitability. On a full year basis, the company recorded a second consecutive year of profitability under non-GAAP measures with adjusted net income of RMB 29.4 million in 2025. This not only underscores that we have captured the right direction for profitable growth, but also demonstrates our ability to translate the operating leverage into sustainable financial returns. Looking ahead to 2026, the company will continue to advance the commercial operations and sales of the EH216-S, expand its nonpassenger business and further penetration into international markets. Full year total revenues are expected to reach RMB 600 million, representing a year-over-year increase of approximately 18%. As our manufacturing and operational systems continue to mature, overseas Sandbox projects progress, global market expansion accelerates and ongoing investment in next-generation products, the foundation for our long-term growth continues to solidify. This requires us to strike a balance between strategic execution and financial discipline in our resource allocation, ensuring that every investment translates into sustainable long-term value. We will remain committed to controlling risks and enhancing efficiency and make our expansion, solidifying the financial condition for the next phase of high quality and sustainable growth and delivering long-term and stable value to our shareholders. Thank you.

[Operator Instructions] Your first question comes from [ Peggy Wang with MS. ]

This is [ Peggy ] from Morgan Stanley. Congratulations on good first quarter results. So I have 2 questions today. First, it's about the license for ground operating crew since we now expect to begin commercial operation in China soon. So could, management team, could you share some more color on the progress of getting those required license for the crew team? And the second one is about the projects in Thailand. Since we are also close to obtaining license for commercial operation, what is the expected timing of revenue contribution? And how will the volume ramp up going forward? So these are my questions.

[Interpreted] This is Wang Zhao. I will take your first question. As mentioned previously, we are still moving forward with the operator training program. All training materials have been submitted to the CAAC for approval, and several courses have already been authorized. We expect the first class for operators to begin in the first half of the year. The good news is that to encourage qualified operators to conduct early commercial operations, the authorities have expanded the number of specially authorized operators for EHang. In the short term, we can conduct commercial operations through these operators. In the long term, we will replenish our talent pool through the operator training program. Thank you.

[Interpreted] This is Conor. I will take your second question. Ever since last October, we have been conducting extensive test flights and trial operations in Thailand. The Civil Aviation Authorities of China and Thailand have communicated thoroughly and they have reached a consensus on mutual airworthiness recognition. This work is now nearing completion. We expected to obtain the first overseas commercial operation license for the EH216-S pilotless eVTOL aircraft following final approval from the Civil Aviation Authority of Thailand. So this would mean that we would truly achieve a normalized urban air mobility services. With the specific to the commercial operations side, they are still under planning. So it will be through the Sandbox initiative. So once obtaining the Sandbox commercial operation permit, the local customers will start to move forward with the purchase orders and deliveries. So we are expecting that to start in Q2. If the progress goes smoothly, there could be dozens of units for the full year of 2026. Thank you.

Your next question comes from Wei Shen with UBS.

[Interpreted] this is Wei Shen from UBS. Congratulations on strong results. So I've got two questions. One is on the current policy changes in the domestic low attitude industries because we saw more [ colors ] mentioning about this industrial sector in the 2 sessions meetings. And my second question is on the overseas market sales guidance, whether management could share any?

This is an Wang Zhao. I'll take your first question. Generally, we believe the overall macro environment in 2026 will be better than in 2025. As you know, the 15th 5-year plan has lifted the low altitude economy to an emerging pillar industry or strategic pillar industry, and the level of -- or intensity of resource allocation and policy support for this industry will be greatly enhanced in the future. And also the development of the low altitude economy was included in the newly issued civil aviation law, which will take effect this July. So this means the industry is entering a new stage where it's going to be ruled by law, governed by law and regulations and standard systems at all levels will be gradually established. This is a necessary path for the new aviation industry. For EHang, we are at the forefront of this industry, and we are contributing first-hand experience to the standard construction. And also, we expected the overall market environment to improve.

This is Conor. I'll take your second question. On the overseas revenue, so the overall revenue guidance for 2026 is RMB 600 million. The overseas revenue in 2025 was in low single digit as a percentage. Looking ahead to this year, as the overseas commercial operations take place in countries like Thailand, the overseas revenue is expected to increase significantly compared to last year. If things progress well, we may expect to see the revenue contribution move into the double digit as a percentage of the overall revenue.

Your next question comes from Laura Li with Deutsche Bank.

So I want to ask about the [ RMB 600 million ] revenue guidance. So what are the assumptions underpinning that? Could you talk about diversifying the revenue through different models or the service revenue versus aircraft delivery or the OEM model versus operator model or the overseas market. So how do you see this play out during this and next year?

So Laura Li, right?

Yes.

[Foreign Language].

This is the conference operator. We have temporarily lost connection with the speaker line. Please continue to hold, the conference will recommence shortly. [Technical Difficulty]

[Interpreted] This is Wang Zhao. I'll take your question. Well, in addition to the human-carrying eVTOL business, we will proactively develop the nonpassenger segment this year such as emergency firefighting, logistics, GD4.0 drone formations and command and dispatch systems. You can see that actually, we delivered 8 firefighting aircraft in December 2025. Meanwhile, during the Chinese Spring Festival Gala, our formation performance of 22,580 drugs earned EHang a new Guinness World Record and attracted significant attention. This, like I said, attracted significant attention for EHang, leading to a surge in inquiries for this business. These are all achievements from our diversified aircraft models and nonpassenger business. With our opening of commercial operations and ticket sales to the public in March, EHang General Aviation will generate some operational service revenue. But of course, the initial contribution to the overall revenue won't be large. But nevertheless, this is a good start. Thank you.

Our next question comes from Fuyin Liang with Bank of America.

I have two questions for the management. The first one is about our commercial operation plan in this month in China. So initially, how do we expect the fleet size of our commercial operation in the 2 cities in China? And given the current fair price, how do we think about the unit economy model? And what's the profit margin of this operation?

[Interpreted] So initially, there will be around 6 to 10 aircraft, and we will gradually increase the number of eVTOL to be used for the commercial operations. And the early bird ticket price for each passenger is set at RMB 299 per person, which will basically cover the flight costs. With the specific data, I think we'll have to give it a period of time before we can disclose further details to the public.

My second question is about our cost control. EHang had a very good OpEx control in the last quarter in 2025. So what's the reason behind that? Looking at 2026, how do we expect the OpEx and also the OpEx to sales ratio?

[Interpreted] This is Conor. I'll take your second question. Yes, you're right. Overall, the [ SBC ] expenses in 2025 were lower in that of 2024. So that resulted in a smaller-than-expected increase in OpEx. Looking ahead to 2026, the year-over-year growth rate for OpEx is expected to be lower than our revenue growth rate. So we are setting our revenue growth year-over-year at [ 18, ] -- from [ 18 ] and our OpEx is going to be definitely lower than that.

Your next question comes from Alan Lau with Jefferies.

Congratulations for the company for the strong results in 4Q and also achieving commercial operation in March. So my first question is regarding to the strong delivery in fourth quarter. So we saw the company deliver units on a single quarter. So I would like to know who are the major clients contributing to such strong delivery? And do you expect further orders from the same clients?

[Interpreted] This is Wang Zhao. The growth in the Q4 deliveries was primarily the result of the year long marketing efforts in 2025. Many of them were not new Q4 customers. But actually, customers who we have been discussing specific operational plans and scenarios over the previous quarters with. And that finally result in the deliveries. And like I said, so the engagement with these clients finally lead to the deliveries in Q4. Some of them were repeat customers. And the key contributions come from clients from Hefei, Wencheng, Xiamen, Guizhou, Sichuan and Guangzhou, and we expect some repeat orders or purchases from repeat customers as well in the future.

That's very clear. And then my second question is regarding to the commercial operation in March. So I would like to know some specifics. Firstly, do you have an exact date on when the app will be launched or the public can book their flights in the program? And then is it [ point A to point A ] flight and each time, it's 1 or 2 persons?

[Interpreted] Yes, our commercial operations will be launched in March. We haven't yet disclosed the exact date as we are still fine-tuning the booking platform, the mini program. But operational readiness wise, we are ready. And as for the route, it is -- the flight is for tourism purposes, and it's from point A to point B, carrying 1 passenger. We believe this is enough to fulfill the needs of the customer.

Your next question comes from Chen Yu with GUANGFA Securities.

[Interpreted] So my question is on the OC application for the existing customers or clients. So what is the company doing on the company side? And what initiatives or efforts is the company putting in to facilitate the OC application? Are there any time lines that can be shared on the OC application for these existing clients? And my second question, I'm not sure whether any other analysts have already asked the same question. Are there any updates on the QC or airworthiness application for VT35? What's the current plan? Are there any adjustments, changes or updates on that?

[Interpreted] This is Wang Zhao. I'll take your first question. There will be 2, so 2 customers that have obtained the OC and their commercial operation will start to accumulate very valuable experience and become a demo of project for the rest of their clients. And we expect the training for the ground crew to begin in the first half of the year. So this will start to build the solid foundation for the expertise that's needed to conduct the commercial operation. And this would also increase the talent pool required to support the commercial operations of other clients. And particularly, our client from Guizhou has already submitted their materials for the OC. And furthermore, the policy environment is much more favorable compared to that in 2025. And we have done a lot of work, and we are ready. So we believe as we make more progress on these applications, there will be more customers that can apply and obtain their OCs in this upcoming year.

[Interpreted] This is Feng Shuai. I will take your second question on VT35 certification progress. In Q4, our VT35 completed key tests, including multi-rotor protective transition and shut down and locked propeller fixed-wing flights. Additionally, we've also held a first TCT meeting for airworthiness review. And we are currently conducting flight envelope tests. We are aiming to obtain the type certification in China within 2 years.

Thank you all. Given that time is limited, let me turn the call back to Ms. Anne for closing remarks.

[Foreign Language] [Portions of this transcript that are marked [Interpreted] were spoken by an interpreter present on the live call.
