1 Good relationship. It depends on your endurance. I can only tell you that the average friendship is now basically 200 yuan. Your friend has a good relationship with you. You have to pay at least 800~ 1000 yuan. You can give Geely numbers if you want to hear them ~ but remember, try not to be singular. Some elderly people who are too particular will care. Try to be a yes man! If you have the ability, you can give more ~ then they will record the guests' money, and sensible couples will reciprocate when you get married!

You don't need red paper, just use red envelopes sold by wedding shops or flower shops outside. Pay attention to the words that should be written on the red envelope, such as "Happy Birthday, Happy New Year" and "Happy New Year". Be careful, hehe.

3 in terms of dress, it is recommended to dress formally. If you don't have a suit, you can wear trousers, leather shoes, an upper-body shirt or a T-shirt (tucked in your pants). If you don't have any help and responsibility that day, casual clothes are ok!
