Wu Youheng and his wife said before their death that they would not buy welfare houses, and most of their income was used to buy books. The parents didn't make a will, but their seven children decided to donate all the most precious books left by their father to the library of Wuyi University. So everyone has nothing of value except a set of father's works.

When Wu Youheng's children recalled their father, they said with deep affection: "My father was very strict with our younger generation and children before his death, and at the same time he was very kind and kind. He left us the impression that setting an example is more important than teaching by example. He mainly tells us how to be a man and what kind of person to be with his own practical actions. Father left us many wonderful spirits, and his spirit will remain in our hearts forever.
