Charlie Richert later recalled the good family upbringing he had received since childhood and said: "It is more difficult to memorize some profound poems than to memorize special terms on human bones. If I can't read medical books well, I'll be scolded by my father, but it's much better than being unable to recite poems and watching my mother silently shed tears for me."

They prefer to boast shamelessly and loudly, saying that he can open the door and lead everyone in."
