According to the plot, we know that pinching is actually eating. Why does pinching have something to do with eating? There are many different sayings in history, among which the following three are the most popular.
First, pinching means sending your tongue away. In ancient times, people on their way out usually went to restaurants to eat. These people on the road were in a hurry and couldn't eat well, so they ate a little food to kill their tongues.
Second, hitting the tip is the wrong way to light the lamp. People need to make a fire when cooking, so it is easy to understand that eating is called lighting a fire.
But why do lighters become sharp? Fogg, a man of A Qing Dynasty, thought that at first people called eating a meal "striking the fire", but the words "fire" and "sharp" were similar, so people called it "striking the tip".
According to ancient novels, we can also see that in the water margin, people also call it striking a light while eating, while in a dream of red mansions, eating becomes a thorn.
3. Pointing is an evolution of Jianghu slang. In ancient times, Jianghu people generally had gangs, and they often used Jianghu slang when they spoke. So it is very likely that it was originally a Jianghu slang, and later it was used by more and more people, so people took it as a formal term.
The above three statements are the mainstream statements about pinching at present. We can see that the word pinch is still very interesting in eating, especially in the first statement, which thinks that pinch is to send your tongue away, reflecting the kind of hard work people have on the road.
