Restricting large subscription refers to the behavior that investors open fund accounts in fund management companies or selected fund consignment agencies, and apply for purchasing fund shares in accordance with the prescribed procedures to reach or exceed the prescribed number.

Subscription refers to the behavior of investors applying to buy fund shares during the existence of the fund and the open subscription period. After the fund is closed, if you apply to buy an open-end fund, it is customarily called fund subscription to distinguish it from subscription during the issuance period. The subscription of the fund is to buy. Listed closed-end funds are bought in the same way as ordinary stocks. Open-end fund is the number you want to buy, divided by the net value of the fund on the day of purchase, to get the number of units to buy. Subscription fee refers to the handling fee paid by investors when they buy fund shares from fund managers during the fund's existence. China's "Pilot Measures for Securities Funds of Open-end Investment Funds" stipulates that open-end funds can charge subscription fees, but the subscription rate shall not exceed 5% of the subscription amount. At present, the subscription rate is about 1.5%, and there are corresponding discounts with the subscription amount.
