Why did Tianan New Materials fall so badly?

Hello, I want to ask Tianan New Materials why it fell so badly. Tianan new materials fell so badly because of the company's economic status. Tianan New Materials 202 1 turned from profit to loss of 57.705 million yuan year-on-year. The competitiveness of the industry is poor, the profitability is average, the revenue growth is poor, and there may be financial worries, so it fell so badly.
