from November 14th to November 18th, 222, the wealth management products of major banks in China suffered substantial losses, and some even suffered a loss of principal, which fell below the net value. Around November 18th, the central bank released a large amount of funds into the market, which stabilized the losses of wealth management products to some extent. By November 21, a small number of banks' wealth management products had picked up. This is only an individual phenomenon, which has improved, but some products are still in a state of loss so far.
