In 58 1 BC, Duke Jing of Jin fell into a cesspit and drowned, which shocked the world. Many people realize that going to the cesspit is actually a particularly dangerous thing, so they think hard. The special product "drowning device" came into being. This kind of "drowning device" is safe and convenient, and soon became popular in China. At first, there were various forms of drowning devices, until Liu Banggan made a "dare against the world" in the period of Emperor Wen of Han Dynasty. There was a famous man named Li Guang, who was brave and unusual. The favorite thing to do when standing upright is to shoot tigers. Where there are tigers, he will beat them. Li Guang shot an evil tiger once while defending the right Peiping, and was injured by the evil tiger. Although the tiger was finally killed, Li Guang was not convinced, so he made the "drowning device" look like a tiger's mouth to show his contempt and contempt for the tiger.
The story spread to the people, and the people were boiling again. Wow, General Li is very powerful. He made a tiger-shaped "drowning device", which is really domineering. So he did, and the "drowning device" had a new name, called Wuwu, but in the Tang Dynasty, the name "Wuwu" aroused the dissatisfaction of Emperor Taizong and Li Shimin. On one occasion, Emperor Taizong of Li Shimin got up at night, and the more he thought about it, the more uncomfortable he became. Why does he think this name is so familiar? It took him a long time to realize that his great-grandfather's name was Li Hu. At that time, he flew into a rage and immediately ordered the name of "Nothing" to be changed, so he changed his name to "Girl".
In ancient times, Chinese taboo was quite serious. For example, Li Shimin's "person" originally meant person, and in order to avoid it, he changed person to person.
