回複： 額外教育費用和大學教育費用的部分:

This part, she must prove that
she does have 額外教育費用 , and 大學教育費用. I even do not know if my children will be able to go to college. And if it proved that my children will go to college,
I will share part of the fee. (Not all, the new father should share part of it too, according to the layer.)

And it also depends on my ability, my salary.
