During the Jin Dynasty, there was a filial son named Wang Xiang. He treated his stepmother with the same devotion as his birth mother. When his stepmother fell ill and desired fresh fish, despite the freezing winter weather, Wang Xiang went to the frozen river. He lay on the ice, and remarkably, the ice melted, allowing two carp to leap out. He took them home to cook for his stepmother.

Similarly, Meng Zong, a man from the state of Chu, was also exceedingly filial to his mother. In winter, when his mother longed for bamboo shoots, Meng Zong ventured into the snow-covered bamboo forest. He embraced the bamboo and wept bitterly, and in response to his profound grief and filial devotion, the bamboo immediately sprouted tender shoots.
