What does the sentence "no borrowing, no courtesy, no aisle" mean?

There are three things you can't lend, that is, you don't give them to gamblers, you don't lend them to lazy people, and you don't lend them to lazy people. Three don't follow the ceremony means that people who haven't seen you for a long time don't follow the ceremony, people who haven't invited you don't follow the ceremony, and people who don't know don't follow the ceremony. "Three noes" means not taking the illegal road, not taking the dangerous road, and not taking the road prescribed by others.

These truths are accumulated by people, because once you lend them, or give them gifts, or even those who take these roads, you will bring yourself some trouble or cause some interference to each other. So don't do these things for your own benefit, and let the other side take the right path.

We know that borrowing money must be lent to people in need. If he borrows money only to satisfy his own desires, I think he might as well not borrow it. Because if he borrows money, first of all, it is difficult for him to pay you back, because they are unable to pay it back, or they don't want to pay it back at all. Secondly, if you lend them money, they will spend it elsewhere, which is also a bad thing for themselves.

And presents. Generally speaking, gifts must be given to people close to you. Because although they bring these gifts, they will return them to you in the future. This is called reciprocity. But it doesn't mean anything to some people who have nothing to do with themselves or haven't contacted for a long time, and they won't give you gifts.

Finally, when walking, we must take the right road, not some dangerous and paranoid roads, because these roads are not good, and we must find our own right road through our own skills.

This is an explanation of the proverb, which teaches us some truths about life.
