Never make friends with gamblers.
I also think that a gambler should never associate with him. If you are near Zhu Zhechi, you will be black, if you are near Mexico. If you have a long-term relationship, you may be addicted to gambling. Another important reason is that gamblers often owe money, so they often borrow money. As friends, they are embarrassed not to borrow it, so it is best not to associate with him.
