Brother-in-law belongs to the woman, so just follow her custom. In Nanping, my brother-in-law's identity is still quite big. When I get married, my brother will help me put on my shoes. There are red envelopes in my shoes (one on each side and one in 50 yuan). My brother will help me put on my shoes. The red envelope is his. On the second day after marriage, the woman will go back to her mother's house, and her brother-in-law will go to the man's house early to call her sister and brother-in-law home soon, and there will be red envelopes. This red envelope can be large, depending on how much the man is willing to wrap, ranging from one thousand to two thousand. Nothing else is special.
