Children were children for the first time.
And the parents were also the parents for the first time.
They were both learning at the same time and it was hard to make everything correct all at once. They were learning and would get better in time, finding the right direction for them to become a proper parent and children to their parents.

Nan Hua couldn't.
Nan Luo couldn't either.
