The bank takes your deposit as a fixed investment by the state, and how much profit is distributed to customers is dividends. Dividends are generally divided into two ways: cash dividends and dividend reinvestment.
Cash dividend refers to the life treasure account paid to users in cash. After the cash dividend, your fund asset share will remain unchanged, but the market value will be reduced, and the reduced part is exactly equal to the dividend.
Dividend reinvestment means that dividends are distributed to users in the form of fund shares, and your fund shares will increase, but the total market value will remain unchanged.
