Hello, Secretary Dong, the company's 23rd quarter report shows that the company's main business profit increased compared with the same period last year. According to the analysis of Biwan APP, the main business profit was -592 million yuan, and the same period last year was -118 million yuan. The reason for the increase in losses compared with the same period last year was that the research and development expenses in this period were 1.21 billion yuan, an increase of 22.27% year-on-year. What is the reason for the substantial increase in research and development expenses?
