The poet Samuel Ullman once said, "Youth is not time, but the state of mind; youth is not peach blossom, red lips, or soft knees, but deep will, grand imagination, and passionate emotions; youth is the deep spring of life." These sentences are particularly suitable for describing Wang Meng. Wang Meng once used this wonderful metaphor to describe the relationship between the elderly and youth. He said that the age of being an octogenarian is nothing more than having too much youth, and a thick youth is the age of being an octogenarian. "What is youth? Cut the old age into thin slices to make it more transparent, and restore youth."
