Qiao Yu can be an aloof national master, or he can be the emperor of the Nine Heavens. People with too many vests will panic. He and his father-in-law are just watching the fun and don't take it too seriously. He and his father-in-law can act in a four-season TV series and stage play with one person and one code.
