Information ````````` "Who is the ancient locust? Take off your shoes and check your nails. ”。 Generally speaking, in Henan, Shandong, Hebei, Shaanxi, northern Anhui, northern Jiangsu and other places, people who moved from Hongdong have a crack in their little toenails, which seems to be two nails, rather than people who moved from Guhuai.

It is said that some immigrants were kidnapped and escorted out of the country. If they need to urinate on the road, they must ask the team leader to untie the rope. So far, going to the toilet in these areas is still called "relieving oneself".
