My husband's surname is Dai, and he said that children are destined to be water. He wants to seek a name in the name of "wood". thank you

It doesn't have to be wood, forest, forest or anything like that. It may be better to hint at "wood":

If it is a girl:

Tortoise shell-Ye Wei, which means lush vegetation.

Shading-tree shading

Boy:

Dai Sang Zi-two kinds of trees, meaning hometown. or

A generation of towering-ancient trees towering, leafy.
