Thank you, Xin. Hello, everyone. Before I go into details, please note that all numbers presented are in RMB and are for the first quarter of 2023, unless stated otherwise. All percentage changes are on a quarter-over-quarter basis, unless otherwise specified. Detailed analysis are contained in our earnings press release, which is available on our IR website. I want to highlight some of the key points here. Following the listing of China's zero-COVID policies, we have observed a robust resurgence in the tourism industry in China, attributable to the significant demands for travel. Together with favorable policies, these have been driving up demands and inquiries for our AAVs recently. This phenomena are in alignment with our current strategic business development focus on aerial tourism. As such, we are confident in our future growth prospects and capabilities in growing our post-certification AAV order pipeline going forward. In Q1, total revenues were RMB22.2 million, up 41.6% from RMB15.7 million in Q4, primarily driven by the increase in the sales volume of EH216-Series AAV products. The deliveries of EH216-Series AAVs in Q1 were 11 units, an 83% increase from six units in Q4. Gross margin was 63.9% in Q1, a slight decrease of 2.2 percentage points from 66.1% in Q4. Despite this minor fluctuation, our gross margin maintains at a high level compared to those of other electrically-powered mobility products such as electric vehicles. This is a result that attest to our competitive strengths and the first mover advantages in the global UAM and eVTOL industry. In Q1, our adjusted operating expenses, which are operating expenses excluding share-based compensation expenses, were RMB50.1 million compared with RMB773.2 million in Q4. The decrease was mainly attributed to the non-cash item of additional provisions for receivables in response to the COVID impact on customers in Q4 last year, while there were increased expenditures for aircraft conformity and compliant tests in the final phase of the EH216-S type certification this quarter. As a result, our adjusted operating loss in Q1 was RMB34.3 million, a significant improvement of 44.1% from RMB61.3 million in Q4. Adjusted net loss was RMB33.6 million, a 43.5% improvement from RMB59.4 million in Q4. Moving on to our balance sheet. We maintain a prudent approach in managing our cash position and assessing our liquidity. As of the end of Q1, we had RMB217.6 million of cash, cash equivalents, restricted cash, restricted short-term deposits and short-term investments. This includes US$10 million strategic investment made by the Qingdao West Coast New Area in Q1, which provides additional liquidity support to bolster our operations and growth. That concludes our prepared remarks. Let's now open the call to questions. Operator, please go ahead.
