Lingshan, Qinzhou City, who knows how Lingshan people guess the code, teach me the rules, how to know whether to win or lose, the more detailed the better?

It's actually quite simple. If you call a number or a sentence that begins with a number, you can give 0, 1, 2, 3, 4. If the finger of a number is called three, you can give 0, 1, 2, 3. If you shout two fingers and the other finger sticks out two fingers, then the total is four, which means you win.
