The so-called villain, should be taboo in the eight characters, jealous and fierce when unlucky, so it can be understood that jealousy is also a villain. In case there is a villain in life, then this villain should be taboo in the eight characters. The eight-character attribute of this villain may be close to the attribute of jealousy. Sometimes when you are weak, you will be a western god and stop being jealous. This is a superficial understanding, so laugh.
I agree that character determines fate. Everyone has his own personality. He was born with something. This is the information displayed in the eight characters. The influence of the acquired environment will change some things, and the quality of personality will change some things in life and situation, but the fundamental things cannot be changed. Potatoes can't change apples, and sweet potatoes can't change pork. Maybe we can make it stronger through the acquired environment.
