"Liao Fang" is a special residence of the Li family in Hainan, where brick houses have been changed except in areas close to the Han nationality. In the past, some people mistakenly thought that "huts" were places where Li Men and women had fornication. Later, after ethnic investigation and cultural workers who went deep into the Li area to experience life, it was confirmed that this hut was actually the daughter's room of the Li people. Because of the Li nationality's habit, my daughter can't sleep with her parents when she is 14 or 15. Men have to go up the mountain to cut wood and build a "cage boudoir", while women are built by their parents. Therefore, the Han people call Li Men's "cage house" a "brother's cabin" and the girl's cabin a "sister's cabin". The older one can live for four or five people, the younger one only lives for one person, and many people live for one person.
