The temporary suspension of fund sales means that funds cannot be purchased temporarily, and some funds will not be sold externally for a period of time, but can only be redeemed. For such funds, investors are generally not advised to redeem them. After redemption, they can't buy.
There are many reasons why the fund will not be sold for the time being, some are to control the scale of the fund, and some are to protect the interests of the holders. Whatever the reason, under normal circumstances, the fund will announce the reason, which investors can check.
