Nanjing's financial management is relatively stable, and the money is getting less and less every day. The reason why the principal is less after buying wealth management products is because the wealth management products that are enough to buy are likely to be non-guaranteed floating income. In a certain period of time, the income of this wealth management product is not good, and there may be a loss of principal when it is redeemed at maturity. This loss of principal will also occur when the income of this wealth management product is not enough to cover the handling fee.
