Whether a daughter marries or lets her son-in-law support the elderly at home depends on her own wishes, so it depends on the actual situation.

There is an only child in the family. According to the concept of carrying on the family line and continuing the incense handed down from feudal society, it is generally to recruit a son-in-law to prepare for the future pension. This situation is common in all parts of the country. But now with the development of society, people's ideas have been updated, and some people have given up the idea of recruiting son-in-law to support the elderly. They just follow their daughter's wishes, and her daughter is willing to marry or leave her son-in-law to support the elderly at home.
