What's the explanation of the lunar calendar?

Sun Xing's friends are enthusiastic, very good at expressing themselves, and also very good at managing interpersonal relationships. They are better than Zi MSI's friends in interpersonal communication. But this kind of person is easy to do things in a hurry, can't do what he can, and has a big personality and is not good at rejecting people. He often becomes a good person and even makes trouble. Sun Xing, who has a good fighting spirit, will be in an anticlimactic state for three minutes if he doesn't have a more challenging new task after reaching his goal, and it is easy to neglect his duties.

The lunar nature emphasizes femininity, introversion and concealment. Sensitive, suspicious and thrifty, but generous to my sweetheart, I like gentle, neat and literary men.
