Why is a son-in-law not required to do housework when he enters his mother-in-law's house Why is a daughter-in-law married to her mother-in-law's house and then expected to do laundry, cook and bring up children, serve her in-laws and help her husband? This is all feudal thinking inherited from China. It is believed that women have to do housework, serve the in-laws, and bring up children. But now is a new era, everyone is equal before the law, no one stipulates that these must be a woman to do. To get rid of this kind of thinking, women must be financially independent, have their own career, have their own pursuit. If a woman has a job, why should she marry to serve others, and work, and go home and do housework, it would be better to be single.
