The steps are as follows:
Log on to the trading platform of the fund you bought, such as bank online banking, or go to the counter, or the third-party platform such as Tian Tian Fund and Jimmy, or the direct selling platform of the fund company official website.
Find the transaction category and see if there is an item called modifying the dividend method. If yes, click Modify directly.
If not, then check the fund you hold, and then look at the end to see if there are any operational items on the fund, such as redemption, conversion, and modification of dividend distribution methods.
Don't worry about it after modification. If there is a fund dividend, it will be reinvested according to the dividend. Dividends will become fund shares, increasing the total share.
