Will it be unlucky if the gold necklace is broken?

I don't know under what circumstances it broke. There are many explanations in Feng Shui, and there are also many relative or wrong explanations in science and medicine. I don't know which one you want to listen to, Feng Shui or science. There are good explanations and bad explanations. Never mind these things. If the chain is broken, it can be reconnected. Little problem.
