Don't believe too much in the benefits of wearing some bracelets, many of which are fabricated by merchants for hype. People who sell bracelets generally say that Kim Jong-bai's greatest function is to soothe the nerves. The biggest advantage of bracelets is to calm the mind and hone the mind. Because I see other people's bracelets are thick and delicate, and my talents are often in a hurry, so I have to calm down and play slowly.
