Would it conflict if we wear several crystals together? Can I wear other items to ward off evil spirits?

I sympathize with you. Last year, my niece encountered too many unexpected difficulties. We have a lot of jade in our family. We all have our own fixed accessories. Whether we wear them or not, we are religious in our hearts. She believed in the meaning of her accessories and had a firm belief in her heart. Nothing went well for my niece that year. What was even more frightening was that she contracted a blood infection caused by a cold and stayed in the isolation ward for more than 20 days without any improvement. It's hard to imagine that life is being threatened. My sister worships Guanyin, and I asked her to find someone to find out what the cause was, and then ask Guanyin to bless her. I found a well-known person to test my horoscope, and he said that my niece's horoscope was reversed, which was extremely bad, and then We went to the Great Buddha Temple together, and I waited outside. My sister went to pray to Guanyin and performed a ritual ceremony. Because I didn’t make offerings to her, she made offerings to her on a daily basis. It doesn’t matter whether she’s superstitious or not. Anyway, my niece has been doing everything since then. Everything is getting better. We believe that first of all, whatever you want to believe in your heart, you must believe it firmly and not think about anything else. I think the amulet plays a protective role (maybe psychological), and you need to do something to change things.
