There are three people but one person is still missing. Since ancient times, no matter how short a sentence is in terms of writing or language, there will be a pause. The pause for "three missing one" is "three, missing one", while the meaning of "four missing one" cannot be paused.

If there is a phenomenon of three missing and one missing in the mahjong game, the three players will directly play according to the previous rules. Other activities that cannot be carried out due to lack of people can also be called "three missing one".

Extended information:

Sichuan Mahjong adopts the popular Mahjong playing style in Sichuan, especially the popular playing style in Chengdu and surrounding areas. There are only three mahjong tiles: tubes, strips, and ten thousand; if there are any missing tiles, you can be fooled; one person is responsible for lighting the cannons; when the tiles are tied, there are bars to increase the bonus. One stroke is one stroke. The last four cards must be able to be fooled.

Sichuan local mahjong also has the following characteristics: plain mahjong, cannot be eaten, must be tied without a door (except in some areas, such as Nanchong), the last four cards are automatically drawn, one shot can be fired multiple times, and the wind blows rain.

Chengdu Mahjong is also called a bloody battle to the end. The gameplay is that one door must be missing. After a family draws their cards, if there are still a specified number of cards on the table, other players must continue the game until the end.
