It is a proverb that rabbits don't eat grass beside their nests. The complete expression of this sentence is that rabbits don't eat grass near their nests, so why run all over the mountains when there is grass near their nests?

The story of this sentence begins with an official named Hu Xueyan in the late Qing Dynasty. At that time, during the war, one of his friends entrusted his wife and daughter to Hu Xueyan. Hu Xueyan immediately patted his chest and said that rabbits don't eat grass beside their nests. I won't have any thoughts about your wife and daughter, let alone lay hands on them.

However, that friend always ignores the power brought by the next sentence, why run all over the mountain when there is grass beside the nest. Hu Xueyan and his friend's wife have been in love for a long time, and her wife is like grass beside the nest. Hu Xueyan is finally with his wife. There is really no grass running all over the mountain. But at the end of the story, his friend never came back, which was in line with the background of the political war at that time. Most of this friend had an accident. If you think so, Hu Xueyan also protects his friends' wives and daughters in disguise.

Since this happened, rabbits don't eat grass beside their nests, which has become a well-known proverb. Moreover, this sentence has been used to describe that a brother can't have any impolite and disrespectful behavior towards his wife and daughter or the girl he likes, similar to the wife of a friend now. But few people really know the next sentence of this sentence: why run all over the mountain when there is grass beside the nest? I believe that if you know this sentence, the protection of wives and daughters between brothers may be higher.
