Hello, young man, I think he is also a very sensible person, and he has the ability to give her a red envelope himself. Even without such good conditions, you have thought about giving her a red envelope, but there are some things I don't understand at home. I tell you, as you said, there is no need to give a red envelope, especially because he is your brother-in-law. Whether he is married or not, as a brother-in-law, there is no need to give a red envelope.

Hello, young man. Remember to buy gifts when you go to your mother-in-law's house during the Spring Festival. If you have money, you can buy more. If you generally follow local customs, your wife knows how much to buy. If his brother is kind to you, you can buy him something he likes, but there is no need to give him a red envelope.

Hello, young man. Finally, I wish you a happy day. Husband and wife are loving and sweet. I wish your family harmony, happiness and well-being, and early birth of your son.
