What do you mean by strange bones?

The word "strange bones" is usually used in martial arts novels to describe a person's special or surprising body bones, suggesting that this person may have the potential to become a martial arts master. Its meaning may be different in different contexts, but it is usually related to special physical characteristics or special qualifications. For example, in Stephen Chow's movie Kung Fu, a mysterious old beggar solemnly said to an innocent and curious child, "Young man, I think you are a unique martial arts wizard, and it is up to you to maintain world peace. I have a secret book, Tathagata Palm, and I will sell it to you for ten dollars when I meet you. " That sounds funny. In different scenes, its meaning is different, but it means that bones are more surprised and very different from ordinary people.
