Hello, the company's prospectus disclosed that there are more than 580 crystal growth furnaces, and the actual annual output of silicon carbide substrates is less than 50,000 pieces. How many pieces can the company produce per furnace per year? Are all the more than 580 crystal growth furnaces fully operational? Thank you

Tianyue Advanced: Dear investors, hello! The company's annual production of silicon carbide substrates in 2021 is about 67,000 pieces, and its production capacity has been saturated in recent years. The company will coordinate the company's production plan according to the order situation. At the same time, the company is constantly making technological breakthroughs to achieve a continuous increase in yield. Thank you for your attention!
