There is a saying in southern Fujian. 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 expression 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, Fuzhou, 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 women and rape them, some practice shooting at China people, and some get drunk and beat pedestrians. It's really evil People in China hate this kind of behavior very much, so when they see a foreign devil, they say that the March 8th Devil is coming again, and they run quickly. Later, the phrase "March 8th Devil" was handed down from generation to generation. In the process of circulation, people simplified it to March 8 for simplicity. Anyone who encounters misbehavior, rude language and bad manners will say: This man is really a bitch.
