The larger the size of bond funds, the higher the amount of subscription funds or the higher the net fund value. Fund size = net fund value * total fund share, which means that the fund size will change with the total number and net fund value.

The fund size should not be too small or too large. If the fund size is too small, the rise and fall of individual heavyweights will have a great impact on the fund performance. If the fund size is too large, it will make the fund management more difficult, and there is no conflict between the fund size and investors' income.
