African women's biased custom-feudal sleeping system

Africa is a continent in the world with relatively backward economic development. There are many indigenous peoples living here, and their lives are relatively isolated from the outside world, so they still retain some very ancient customs and cultures. Some cruel bad habits condemned by modern society also plague the residents here all the time, especially some prejudices and customs against women, and even cause AIDS to run rampant here. One of them is the extremely feudal system of accompanying sleeping.
