Straight wood(míng yàn zhí mù)

Straight wood

The ancients believed that the wild geese follow the sun and the trees follow the sun. It's a metaphor for good talent.

Idiom and allusion [source] "the biography of Yuan ang in the book of Liang Dynasty": "the humble official of the eastern Kingdom, who can learn and do what he wants to do, has no ribbon and no crown because of the special singing of wild geese and straight wood."
