Good day, ladies and gentlemen. Thank you for standing by, and welcome to the EHang’s Fourth Quarter and Full Year 2020 Earnings Conference Call. At this time all participants are in a listen-only mode. Later, we’ll conduct a question-and-answer session and instructions will follow at that time. As a reminder, we are recording today's call. If you have any objection, you may disconnect at this time. Now I will turn the call over to Julia Qian, Managing Director of The Blueshirt Group Asia. Ms. Qian, please proceed.
