Why is the Chinese thought of son preference still so serious?

The root cause of the Chinese people's preference for men over women is feudalism, the old saying goes: "No filial piety has three, no later for the big. A lot of people want to have a son to send to the end, no matter how bad the son born, or his heart. Most people think that the daughter married out of the water out of the water, when the time is to take care of the in-laws forget the year home, no contribution to the family, there are a lot of old people is to hold the old saying when the holy orders, the birth of a son to me to continue to be pathetic a passer-by 218.19.53.* Guangdong this side of the case of overbreeding is very serious, which is with China's "male child preference" idea is very big. This is with China's "son preference" idea has a lot to do with, especially rural people they feel that the boy is to pass on the generation; pass on the generation is frankly a family name; this kind of ignorance, backward thinking has become a lot of family separation of the reason. In order to make this kind of supernumerary guerrilla extinction, the first is to improve the cultural quality of the people, another best way is: can allow two children, but must be a child with the father's surname, a child with the mother's surname; on the household registration if the birth control office can be implemented according to this, supernumerary will not have any meaning, I believe that China's "male child preference" thinking will be generation after generation, and will not cause so much trouble. I believe that China's "son preference" ideology will fade away from generation to generation, and will not cause so many family tragedies. 。。。。 I suggest that the state should amend the relevant laws and regulations; so that the national "family planning" policy of the country in the direction of benign development
