No, but the selling fee does not have to be excluded from the fund income. If you still hold the fund, the selling fee will be deducted from the investor's income. If you don't hold the fund, the investor's income is all the income.

Fund income = (current net value-net value at the time of purchase) * fund share handling fee. Fund income is determined by the investment target. If the investment target goes up, then the fund goes up, investors gain income, and the investment target goes down, then the fund goes down and investors suffer losses.
