Guess where the code came from.

Guangxi. It is a form of fencing in which people in Guangxi Zhuang Autonomous Region play a reward and punishment game with Cantonese pronunciation in southern Guangxi as the main voice and Guiliu dialect in western Guangxi as the supplement. "Code guessing" is a game of adding numbers. When two people reach out and shout the code at the same time (one person can only make one hand), one of them shouts that the sum of the fingers of both hands is victory.

Precautions:

Code guessing and coding should start at the same time, just like guessing stone scissors cloth. When we call stone scissors cloth, stones or scissors will be produced. When you guess the password, you must give it at the same time. Also, the number of yards is called out to each other.

Except winners and losers, if everyone guesses the same number, it is "simultaneous". You can ignore it and continue to guess, or you can guess again without swallowing it.

It should be noted that code guessing and code output need to conform to a certain logical relationship. For example, if you guess the code is 9 and you bid 3, even if the opponent bids to the highest 5, it will add up to 8. Anyway, there will be no 9. For example, if you guess that the code is 3, but your code is greater than 3, you will know that you lost without thinking. These are called "garbled codes" or "error codes".

Most people have higher requirements, and generally "wrong code" counts as loss; There are also some young people who made two mistakes before losing.
