What if relatives send money on business trips?

You mean your own relatives work for you, and they don't want you to give money to others? I think you should also give him money for this matter, but he insists on not giving it. Maybe your relatives think you are relatives, so he is right to help you, and he is embarrassed to accept your money. But people don't want to go back. You let people do things, remember, people are good to you. If there is a suitable opportunity in the future, I will repay others. You can also find out what his family lacks and buy her something. If he doesn't want you again, say he bought something. It's no use if you don't want me to keep it. This is not a waste. Just stick to it. As the saying goes, a drop of water is rewarded with a spring. Although relatives also pay attention to reciprocity, it is right for you to let relatives do things and send money to others.
