Generally, open-end funds can be purchased during working days, unless the capital preservation fund is closed for two years or the fund company announces otherwise. China Merchants Pioneer is not a capital preservation fund, of course it can subscribe. June 5 is the equity registration day, which means that all registered investors can enjoy dividends after the fund is opened on that day. Subscribe on the same day to participate in dividends. It only takes two to three days for the fund share to arrive. After dividends, the net value of the fund is ex-rights. Don't think that redemption can earn dividends:)
