Hello. I see that the company has more than 3,000 people and a revenue of 1.6 billion. What is the proportion of the 3,000 people mainly distributed in production, sales, and R&D? It feels like there are too many people? Is it for future reserves or something else?

Xusheng Shares: Dear investors, hello! As of the end of 2020, the company has a total of 1,862 employees, including 225 R&D personnel, accounting for 12.08% of the total number of employees. Thank you for your attention!
