When I read the name of Amitabha, I yawn and cry. Why?

This is a good phenomenon, because when you study Buddhism, your body and mind are good, so you force out some primitive karma of your body, that is, negative energy, just like a martial arts master who forces poison with internal force. If we don't force out these karma, it may drag our feet at a critical time. Because you broke evil, you began to practice seriously, and your unjust relatives and creditors were unwilling. If you practice well and jump out of the six divisions in the wheel of karma, where can you collect debts? So now he wants to get in your way. But as long as you don't take him to heart, it will slowly disappear. The merits of chanting Buddha at ordinary times must be returned to all sentient beings who were hurt and killed in the past, sincerely repent to them and ask for their forgiveness. Slowly, they will also become your fellow practitioners and protectors.
