How did Mencius educate his son?

Meng Mu chooses its neighbors. When Mencius was young, his father died young and his mother never remarried. They live next to the cemetery. Mencius learned to bow down and cry like an adult and played a game to deal with funeral. Meng Mu saw it: "This is not the place where I used to settle my children!" Go to the market with Mencius. When they arrived at the market, Mencius and the children in the neighborhood learned that businessmen were doing business and slaughtering pigs and sheep. Meng Mu saw it and said, "This is not the place where I used to settle my children!" So they moved again. This time, they moved near the school. At this time of the first day of the summer calendar every month, officials go to the Confucian Temple, bow down and treat each other politely. Mencius saw it and learned to remember it one by one. Meng Mu said: "This place can be used to place children!"
