(crossing your legs) Why is it called crossing your legs?

The origin of Erlang's legs The poet Liu Shahe once wrote the article "Explanation of Erlang's legs", which explained the origin of Erlang's legs with great interest. He pointed out: "Erlang Leg" is said not only in Sichuan Province, but also in other provinces. This is the sitting posture of Erlang God. The statue of Jiro in the main hall of Wangchuan Temple in my hometown and the old statue of Jiro in Erwang Temple in Dujiangyan, Sichuan are all like this. Erlang God is said to be the second son of Li Bing, the king of Qin, who helped his father to chisel away from piles, cut jiaozi, kill pests and seal Erlang God after his death. There are Yang Jian and Erlang God in The Romance of Gods. He is a legend, a novel, and even more absurd ... Erlang God's sitting posture is absolutely out of Confucian rules. The so-called cross-legged, in professional terms, should be yubu. According to legend, Yu managed water, tried his best to open ditches, stayed at home for ten years, and became a cripple with one leg stiff. When I was a child, I saw the wizard's practice, jumping with one foot and lifting with one foot, which is called Yu Bu, and it is imitating Yu. The statue of Erlang God in Dujiangyan is shaped as a sitting posture with his right leg resting on his left leg, which is also imitated in. In the 1980s, Erlang's legs disappeared and the mystery disappeared. Old plastic has the tail of ancient mythology, which shows where we come from and is also a respect for ancient culture. "It is really not worthwhile to be transformed into a migrant worker to repair water, so that the word Erlang legs is lost and it is difficult for future generations to find it."
