The minimum monthly 200 yuan for fixed investment funds is 300 yuan or more, but some fund companies or banks require a minimum monthly.
You can go to China CITIC Bank to make a fixed investment in the fund. It is best to choose a fund with back-end fees for fixed investment, so that there is no handling fee when buying it every month, but it can only be redeemed if it is held for the time specified by the fund company (ranging from 3 years to 10 years), and there is no handling fee.
