What is the meaning of "Three Sevens to One"?

Sanqi Doubling is a traditional Chinese game of chance, usually with multiple players, in which the rules of the game are that two players repeatedly compare sizes until one of them wins. The game is best known for the mnemonic "Sanqi Dou Yi", which means three threes and a seven. The game not only helps participants' hand-brain coordination, but also strengthens their teamwork spirit.

The mnemonic "three sevens and a seven" is also often used to describe a skillful skill or a skill in finding a problem. For example, a person who cracks a code or finds a bug in a machine can say that he is very good at "three sevens to one". The phrase is also often used to describe people's resourcefulness and acumen at work or in life.

The catchphrase "three sevens to one" also appears in movies. For example, in the movie "Dee's Dragon King of God's Capital", Dee used "three sevens to one" in his reasoning and successfully uncovered the truth of the murder case. This little game is both entertaining and skillful, and is a very interesting cultural phenomenon.
