How to play divination by the old turtle?

This is a card game called Wang Bagua. It is said that Mao Zedong loves to play, especially before making a big decision, he always has to solve it. Chiang Kai-shek is said to be playing, but he never unties.

The chance of unbinding this racket is very small, almost every 20 rackets can be unbinding. Posing is like taking pictures and solving the right cards. I love playing, but it's not easy to untie. You turtle lovers might as well try this gossip.
