What are the heinous customs and practices in ancient China?

In ancient China, foot-binding was the most common bad habit to oppress women. Tied tightly with cloth strips, the female foot becomes smaller in fracture and distortion, and finally becomes a "three-inch golden lotus" that is less than one grip. When did the bad habit of foot binding originate? Although there are some different views and viewpoints, contemporary academic circles still generally believe that foot-binding originated in the Northern Song Dynasty or earlier in the Five Dynasties and Ten Kingdoms, was popular in the Southern Song Dynasty, popularized and miniaturized in the Ming Dynasty, and flourished in the Qing Dynasty, with a history of at least 1000 years in China. Regarding the discussion of foot binding, the mainstream view holds that it is an extremely ignorant and cruel custom.

Martyrdom is the custom of being buried with the living in ancient funerals, the product of class confrontation and a cruel and barbaric religious act. It appeared at the end of primitive society and prevailed in the era of slavery. Most of the victims are close relatives, priests, followers and prisoners of war of the deceased. Most of them were hanged, poisoned, buried alive and buried in graves. Although the phenomenon of martyrdom in ancient China was very popular, martyrdom was not unique to ancient China, and martyrdom occurred in many nationalities in the world. Ancient Egypt is one of the countries with rich human funeral culture, and its history of human martyrdom is earlier than 3000 BC, not later than the first dynasty.
