No Man Knows What He Owes to His Parents Until He Comes to Have Children of His Own in Chinese / Japanese...

子を持って知る親の恩 literally translates as: Only after you have a baby, you would appreciate your parents (feel the way they do, etc).

This is a bit like the “walk a mile in another man's shoes” saying. Basically, it's about you cannot fully understand the plight of others until you experience it yourself. It also shows appreciation for the plight of parents.

This Japanese proverb can also be translated a few more ways:

No man knows what he owes to his parents till he comes to have children of his own.

One knows not what one owes to one's parents till one comes to have children of one's own.

Only after you have a baby, you will appreciate your parents or feel the way they do.

Only after becoming a parent yourself do you realize how much you owe [how indebted you are] to your own parents.
