1. Unreasonable provision ratio: Amoi's bad debt provision ratio has been low for a long time, lower than other peers. This has caused the company to face some non-performing loans, which will generally affect its operating performance and financial situation.

2. The company's operating risk is relatively high: Amoi Electronics has a relatively high competitive pressure in domestic and foreign markets, and its operating risk is correspondingly high. In this case, if the company still maintains a low proportion of bad debt reserves, it is easy to have liquidity risk and credit risk caused by bad debt losses.
