How did zombies come into being?

I adjusted it to see if it was right. I'm interested in zombies ~ I'd better become a zombie ~ Haha, it's just the kind of thinking zombie that says it doesn't exist, and I'm not sure about my research style. Amateur, of course, purely a hobby. My master said that zombies are usually formed in places where feng shui is particularly dangerous, but there are also places with good feng shui, but the chances are small, but the zombies formed are particularly fierce. The grave robbery industry is most afraid of encountering zombies. In jargon, ordinary dead bodies are called zongzi. Zombies are big zongzi (few people meet them). At present, the so-called zombies in Hunan are only dead bodies, and few people can become zombies after death. For example, there are two easiest ways to identify whether there are zombies. The first method is to see if there are any locust trees nearby. If there are locust trees near the cemetery, it is best to belong to Feng Shui, which is the so-called town ghost. If the people buried belong to water, fire and gold, there may be zombies. And it must be relatively empty around, and the moonlight can shine in. If the locust tree dies, it is recommended to go at once. The second is to light a white candle in front of the curtain at midnight on the Double Ninth Festival. Be careful not to have wind. If the flame of the candle turns green and then goes out, run at once, or it will be finished if it is caught by a zombie, so the chance of becoming a zombie is very small. If you find a wild cat in front of the curtain, please leave at once. My master is 67 years old. He said that his master was my grandfather, and he was only 17 years old. He and his grandfather were invited to a place where all the chickens and ducks died. My grandfather used gossip to calculate the result and dug up the land. There was a man in his twenties in the coffin. His face was very white and did not rot, but he immediately let me burn it. After that, my grandfather told me that it would be a zombie. I believe me.
