What's the difference between three cups, four cups and five cups and six cups?

"waist three in four" and "Wu Yao he Liu" are terms in Chinese mahjong, but their meanings and usages are obviously different.

1. Meaning: Yao Sanhe Si originally refers to the vulgar and vulgar language when playing mahjong, which probably comes from the shouts of one, two, three and four, five and six. Later, the scope of use expanded to refer to obscene and shameless words and deeds. Wu Yao's drinking six refers to the rude words that are slightly more civilized than Yao's drinking four. It refers to the old expressions used by dancers in the old China ballroom and hooligans on the beach to describe their bad conduct, debauchery and fraud.

2. Usage: waist three in four has a wide range of uses, which can not only express the accusation of uncivilized behavior of others, but also describe some inappropriate behaviors of oneself. Drinking too much is more used to describe the behavior of dancers and hooligans, and it can also be used to accuse others of disrespectful or impolite behavior.

Generally speaking, Yao Sanhesi and Wu Yao Liuhe are derogatory idioms, but their usage is slightly different. Attention should be paid to the context and the accuracy of words.
