1, the parent fund generally refers to the FOF fund, and its full English name is FundofFunds, that is, the fund in the fund is a fund with the fund as the investment target. Simply put, the fund invests in stocks, bonds and currencies, while the FOF fund is an investment fund.

2. There are two concepts of sub-fund, one is FOF and the other is graded fund. Here, I mainly talk about the sub-funds in the FOF fund, and I won't talk about the other one. FOF Fund is a special fund that invests in portfolio funds. Compared with sub-funds, FOF funds are not directly involved in investing in stocks or bonds. Moreover, the parent fund itself is a whole, so the starting point of subscription is high, and the sub-fund is part of the split parent fund, so the starting point of subscription is low.
