The reason why the money fund can't withdraw cash in full is because the user's assets contain the income that has not been carried forward, and this part of the income can only be withdrawn after being carried forward. When the user still has the income that has not been carried forward, it can be sold after the trading day of 15:00.

Non-monetary funds can't be taken out completely, because non-monetary funds are sold according to the amount specified by the share rather than the amount, and the data on both sides may be different.
