Just like in a casino, you have the ability to see the cards of both sides of the game (the ability to learn the number of tricks), and then you tell one side (the secret is leaked), so that one side wins and the other side loses. Don't you think the loser will give you trouble? It's also possible for them to beat you, scold you and kill you, right? This is what's coming to you.
Of course, few people really learn the tricks well after learning them, and most people just learn a scratch. Just as there are many people studying mathematics in China, only one Hua Luogeng has been produced.
So, if you learn the tricks, if you don't have the ability to see others' cards clearly, others won't kill you, right?
