What does the fortune-telling eagle bone mean?

Eagle bone: I was born with eagle bone, and I am proud of my character. I try my best to do the best thing for my friends. I have to guard against going down the mountain early, and my sword will be drawn early.

The human body needs bones to support and match. It is said that the quality of bones can also determine a person's honor or disgrace.

For example, Fan Li, the richest man in the Spring and Autumn Period, not only has a pair of good bones, but also observes other people's personalities. Perhaps the peace of his life has something to do with this ability. He once wrote a letter warning Wen Zi: "Birds are exhausted, good bows hide, cunning rabbits die, and running dogs cook." King Yue has a long neck and a sharp mouth like a bird's beak. This kind of person can only share joys and sorrows with him, but can't share happiness with him. Why don't you leave? "But the doctors who had been serving the King of Yue were reluctant, some with a grain of salt, and didn't leave. Finally, they were driven to commit suicide by the King of Yue. However, he resolutely gave up and left the country of Yue, which defeated Wu and could enjoy the success, and roared off. Later, he went boating in rivers and lakes and made a fortune in business.
