Idiom story of kneeling for "feet"

Idiom story: cut your feet and fit your shoes

According to Huai Nan Zi Shuo, during the Spring and Autumn Period, King Ling of Chu led an army to attack Xu, and his brother abandoned his illness and was encouraged by courtiers to take the opportunity to kill two sons of King Ling. Hearing the news, Ling Wang was heartbroken and hanged himself. I gave up my illness and didn't know that the Ling Wang was dead. Because there were two brothers on it, I didn't dare to inherit the throne at once, so I made my brother's son Woods king. When he learned of the death of the Elf King, he gave up his illness and consulted Wu Chao. Encouraged by Wu Chao, he gave up his illness and forced Woods to commit suicide. He became a king named Wang Ping.

Jin Xiangong, the monarch of the State of Jin, liked the beautiful woman Li Ji very much and married her. He also plans to let Li Ji's son Xi succeed him as the Prince. But Gong Xian already has three sons, Zhong Er, Yi Wu and Shen Sheng. Among them, Shen Sheng is very popular, and most people think that Shen Sheng should become a prince. When Li Ji saw this, she used a trick to sow discord between Gong Xian and the three sons. Later, Gong Xian really listened to the rumor, made Shen Sheng commit suicide, and sent troops to capture Zhong Er and Yiwu, forcing them to flee abroad.

These two stories show that the flesh and blood originally respected each other, because there were sinister and treacherous bad guys playing tricks on each other, so that the uncle wanted to kill his nephew and the father wanted to kill his son. It's like cutting off a part of your feet when your shoes are small and a part of your head when your hat is small.

The idiom "cutting one's feet to fit one's shoes" means ignoring the objective reality and copying it mechanically.
