When did China begin to practice foot binding?

The collection of beriberi was written in the first year of Xianchun (AD 1274). Since the Song Dynasty, when women were four or five years old, people began to bind their feet. If they are old and the mobility of joints and ligaments disappears, it is not only difficult to wrap them small, but also more painful to wrap them, so they can be wrapped at the age of seven or eight and wrapped after the age of ten. When is the best time to start packing in a year? Because the feet are burning when wrapping, it is generally recommended to start wrapping when the weather is cold in autumn. Gu Tieqing, a A Qing, said in Jia Qinglu: "On August 24th, glutinous rice and red beans were cooked into balls to offer sacrifices to the stove, so the little girls chose to bind their feet on this day, saying that the binding of feet with eating balls could make their calves soft." Because foot binding is to worship Little Foot Niang, and August 24th is Little Foot Niang's birthday, most women will choose that day to start foot binding, and some people choose "auspicious day for foot binding" to start foot binding.
