Explanation:
Mencius' mother moved three times in order that Mencius could have a good learning environment and concentrate on her studies without interference and influence from neighbors and villagers. Once Mencius played truant, Meng Mu broke the loom in order to educate Mencius. If the shuttle is broken, the cloth can't be woven and the study will be lost. You can't learn to fish for three days and dry the net for two days.
Extended data:
Meng Mu moved three times:
The first time: Mencius lived near the cemetery when he was a child, and people often came to worship his ancestors. Mencius followed suit and played a funeral game. Meng Mu thought it was not suitable for children to live here, so he moved his family to the market, which was a move.
The second time: the market is very lively, and vendors slaughter animals and sell meat. Mencius studied the practices of people in the market. Meng Mu felt that this was not conducive to the growth of Mencius, so his family moved to Gong Xue, which was the second time.
Third time: After moving to Gong Xue, Mencius learned the etiquette of bowing and advancing and retreating in the imperial court. Meng Mu thinks this is something a child should learn, so he lives in this place.
