The variability of fund size is different. Closed-end funds have a definite duration (in China, the duration is not less than 5 years), during which the issued fund shares cannot be redeemed.

Although this kind of fund can be raised under special circumstances, it must meet strict legal conditions. So in general, the size of the fund is fixed.

Extended data:

If you buy a fund on a trading day (Monday to Friday when the stock market opens), it will generally be after T+2 (T is the trading day when you buy the fund, and +2 is two trading days after the day you buy it).

You can see the share of the fund you bought. Reservation funds should be purchased on non-trading days, and will generally be postponed to the next trading day for trading.
