Common types of funds are money funds, bond funds, mixed funds, index funds, stock funds, special funds and so on. According to the different ways of establishment, funds can be divided into open-end funds and closed-end funds. Investment funds need to pay a certain fee. Fund handling fee refers to the fee paid to the sales organization when buying and selling funds, which is used to compensate the expenses incurred by the fund sales organization in handling fund trading procedures. The handling fee of the fund is a one-time fee, which means that you have to pay the handling fee when buying and selling the fund, and you don't need to pay it at other times.
