1. Whether there is a commission for the handling fee of the fund depends on the type of fund. Commission is the intermediary fee charged by securities companies when investors buy and sell stocks through them. At present, the commission standard of most securities companies is 0.15-0.03%; Buying open-end funds through securities companies does not charge a separate commission, but a corresponding subscription rate; Buying closed-end funds through securities companies has the same commission as stocks.

2. Fund expenses generally include two categories: one is the expenses borne by fund investors in the process of fund sales, mainly including subscription fees, subscription fees, redemption fees, fund conversion fees, etc. These fees are generally charged directly when investors subscribe, purchase, redeem or convert. The subscription fee can be charged when investors buy funds, that is, the front-end subscription fee; It can also be charged when investors sell funds, that is, the back-end subscription fee, and its rate is generally decreasing according to the holding period. The other category is the expenses incurred in the process of fund management, mainly including fund management fees, fund custody fees and information disclosure fees. These expenses are borne by the assets of the fund. For money market funds and some bond funds that do not charge subscription and redemption fees, a certain fee can also be extracted from the fund assets at a ratio of no more than 2.5‰, which is used exclusively for fund sales and services to fund holders.
