What is youth? A woman who has gone through vicissitudes of life said: Youth is the tomb of love, it is better to be careful. A woman who is different from the outside said shyly: You should fall in love before you can be considered perfect youth. A bookworm smoothed his hair and said seriously: Studying hard is the key to youth, otherwise you will be like a straw bag when you go out into the society. A carefree woman said dismissively: Youth is like a night dish, you can either eat it again or throw it away.
