First, the emotional twists and turns, the emotional road of a man with a pure yin character is tortuous, and it is easy to break up with his predecessor and kill each other for various reasons.

People with eight-character sterling silver are weak, and although they live a long life, most of them are more or less sick. Therefore, people with pure yin in the eight characters will not be related to physical labor in most of their future jobs, mainly mental labor.
Third, people who have a successful career and are pure in eight characters are often mental workers, so their jobs are well-paid jobs. These people are very successful in their careers, and most of them will have no problems in their future lives.
