Ladies and gentlemen, thank you for standing by, and welcome to the Canaan Inc., First Quarter 2021 Earnings Conference Call. At this time, all participants are in a listen-only mode. After the speakers' presentation -- after the management’s prepared remarks, we will have a question-and-answer session. Please note this event is being recorded. Now, I'd like to hand the conference over to your speaker host today, Mr. Shaoke Li, Board Secretary of the Company. Please go ahead, Mr. Li.
