Although the fortune teller is very old and your answer is very professional, I still don't understand what it means to commit a poisonous sword. Can you tell me something?

This kind of problem is a fortune-telling professional term, which requires certain knowledge, such as eight-character fortune-telling, such as the five elements generating grams, the coexistence of evil spirits and so on. It is not easy to analyze it in very popular words. In short, committing a poisonous sword is basically similar to having an evil spirit in life. If the Lord has this evil spirit, the villain is easy to ambush and be wronged, and it is easy to get Yin strange diseases and commit evil spirits. Therefore, it is necessary for the Lord to do good deeds and accumulate virtue in order to make Yin invisible.
