The allusion of traditional family education is

Wang Xiangzi is from Linyi. Pure filial piety. His biological mother died when he was very young, and his stepmother Zhu was mean and spoke ill of him many times in front of his father. So he lost his father's love at an early age and was often called to clean the cowshed. His parents are ill, so he can't take care of them day and night. Once her stepmother wanted to eat live fish. It was so cold that the river froze. Wang Xiang took off his clothes and prepared to break the ice to catch fish.

The ice broke automatically and two carp jumped out of the water. Wang Xiang took them home (to his mother). Stepmother wanted to eat roasted yellowbird again. Dozens of yellowbirds flew into the tent, so he took them to worship his stepmother. The villagers sighed in surprise, thinking that Wang Xiang's filial piety touched the heavens and the earth.
