What does "March 8th" mean?

March 8th is the standard "provincial curse" in Taiwan Province Province. The so-called "March 8th Festival" should be used to curse a woman, which means "this woman is frivolous, reckless, crazy and not serious enough"

There is a saying in southern Fujian called "March 8th Festival". This is a swearing word, which refers to those who are not serious or whose behavior and language do not conform to etiquette and moral norms. How did the proverb "March 8th" come from?

In the late Qing Dynasty, Eight-Nation Alliance invaded China, and the corrupt Qing government was forced to sign many treaties with Eight-Nation Alliance, and opened five ports, including Ningbo, Shanghai, Qingdao, Xiamen and Guangzhou, as trading ports. Since then, foreign invaders have run amok on the land of China. At that time, many foreign devils were stationed in Xiamen, Quanzhou and other places. On the third and eighth days, foreign devils ran around in droves. Some drive on the rampage, some rob and rape women, some practice shooting with China people as targets, and some beat pedestrians through drunkenness ... It's really evil. China people hate this kind of behavior very much, so when they see foreign devils, they say "March 8th devils are coming again" and run away.

Later, the phrase "March 8th Devil" has been handed down. In the process of spreading, people call it "March 8th Festival" for simplicity. When people meet people who are misbehaving, rude in language and don't obey etiquette, people will say, "This man is really a bitch."
