I feel like sharing my experience of a 防鬼辟邪符 I have used. Note: the 符 is not from 梁思浩. My boyfriend has seizure. I placed the 防鬼辟邪b 符 beside his bed. That 防鬼辟邪符 is too powerful and caused his seizure more often than usual. I immediately removed the 符, then he was fine. Likely, all human bodies are different, but pay attention to this.
