Why is rural China so feudal?

It's easy to stand upstairs and talk. Rural areas have the actual situation in rural areas. The more underdeveloped areas, the greater the role of men in daily life. In rural areas, one man often helps more than ten women. Can we not have a man? Feudal thought has not been eliminated, but it is still very serious. Not only is there a serious preference for boys over girls, but there is also a serious sense of hierarchy. The patriarchal ideology is more serious in rural areas than in cities. Of course, there are economic reasons. There is no old-age security in rural areas, and it is more realistic to raise children to prevent old age. However, the feudal hierarchical concept is very serious in both urban and rural areas.
