It means that even if you die of poverty, you can't rent your father-in-law's field, because this young man is equivalent to being adopted by wife, being looked down upon by people, and starving to death will not enter the radish garden, because eating too many radishes is not good for your health; People who are poor can't be short-sighted. No matter how poor they are, they can't afford to eat, and they can't steal radishes from other people's radish gardens. They must have their own backbone. .
plowing for the old father-in-law's family is equivalent to the man thrusting the door backwards. In ancient times, it was very difficult for the son-in-law to give up his original surname, and he had no position in the family, which was very embarrassing and probably would not be rewarded accordingly. Going into someone else's radish garden when you are starving will be considered as stealing radish.

First, the son-in-law is the man who goes to the woman's house and the child takes the mother's surname. Originally, it was a matriarchal family marriage system, which was the development of ancient marriage customs such as wife's residence and service marriage. During the Qin and Han Dynasties, the form of son-in-law adoption had the nature of "son-in-law serving". After the Song Dynasty, the son-in-law became a kind of "son-in-law's replacement" and "son-in-law's support for the elderly", and the daughter-in-law had no male children, so the son-in-law came to the door to continue the patriarchal clan system, supplement the labor force and support the elderly in the daughter-in-law.
2. Proverbs are similar to idioms, but they are colloquial and easy to understand, and generally express a complete meaning, with almost one or two short sentences in form. Proverbs cover a wide range. Proverbs, like idioms, are part of the whole language, which can increase the distinctiveness and vividness of the language. But proverbs and famous sayings are different. Proverbs are the practical experience of working people, while famous sayings are what celebrities say.
