The income statement shows a heavy interest burden, reaching 30% of operating profit in 2021, a balance sheet showing long-term borrowing of 5.2 billion, and the company has little net worth. The company's accounts receivable is also very high, reaching 2.5 billion, reaching 80% of revenue, which is very abnormal. At the same time, the company's inventory shares reached 6.5 billion, in the case of such a high debt ratio to retain this number of inventory stocks is very unreasonable, the stock is not very attractive.
