Wechat sent someone to borrow money. How many people usually borrow it?

Very few. If the borrower is unfamiliar with the people in the group and does not have much credibility in the group, then only a few people or even no one will borrow it, because it is difficult for people who are unfamiliar with themselves or do not have enough trust to lend a helping hand. In this case, the probability of borrowing money and the number of people will be very low, and a group of about 50 people is only about 1-2 or even 0.
