During the Warring States Period, there was a great scholar Mencius. Mencius was very naughty when he was a child. His mother spent a lot of effort to get him a good education! Once, they lived next to the cemetery. Mencius and his neighbor's children learned to bow down and cry like adults and played a funeral game. Mencius' mother frowned when she saw it. No way! I can't let my children live here! Mencius' mother took Mencius to live next to the market. When he arrived at the market, Mencius and his neighbor's children began to learn how businessmen do business. Bow to welcome guests, entertain guests, bargain with guests for a while, and behave well! Mencius' mother knew this and frowned: This place is not suitable for my children to live in either! So they moved again. This time, they moved near the school. Mencius began to be orderly and polite, and liked reading. At this time, Mencius' mother nodded with satisfaction and said, This is where my son should live! Later, people used "Meng Mu's Three Movements" to explain that if people want to learn good habits, they should be close to good people, things and things!
