If you buy a fund, if the principal is not enough, you need to pay back the funds. However, under normal circumstances, the fund's net value will generally not fall to 0. If the net value of the fund continues to fall, then the fund manager will take appropriate measures to stop the loss. If the net value falls below redemption, once the fund liquidation standard is reached, the fund manager will also announce the fund liquidation, which will not lead to the reversal of losses.

Fund, in English, refers to a certain amount of funds set up for a certain purpose. It mainly includes trust and investment funds, provident funds, insurance funds, retirement funds and funds of various foundations.
