My girlfriend is very loyal. What should I do?

Nothing at first, just because some people believe and some people pursue. If someone wants to overturn his or her point of view, he or she will argue with you. You can't beat such a superstitious person. They would rather sacrifice a lot to prove their point of view, and the result should be the result of fortune telling. You need to tie the bell to solve the problem, and then take your girlfriend to a fortune teller for divination. Never argue with them.
