What is the reason why my friend WeChat borrowed money and didn't receive a reply?

Wechat borrowed money, but my friend didn't return. It means that the other party may be busy and didn't see your news. Or maybe the other party doesn't want to lend you money. I suggest you stop asking such questions. After a day or two, if the other party still doesn't reply, it means they don't want to send you the money.

Try not to borrow money between friends. If you really need money, you'd better borrow it from your family. Especially ordinary friends, don't end up having nothing to do with friends because of the problem of borrowing money.
