Why is it called "relieving oneself" to go to the toilet?

Why many areas are called toilets? To relieve myself? This has to be traced back to a great migration in the Ming Dynasty, which was produced in this migration? To relieve myself? This word. During the Ming Dynasty, the occurrence of natural disasters and the remains left by previous wars made the originally prosperous Central Plains uninhabited. In order to promote the development of the Central Plains, Ming Chengzu tried to get people from other places to move there.

So I chose the Shanxi area where Ankang people live in compact communities. Of course, this is not voluntary. At that time, honest officials publicized that people who didn't want to go to the Central Plains registered under the big locust tree, and when they arrived, they were tied up, and the people found themselves cheated. Many old people and women are crying. After all, they are leaving the place where they have grown up for decades. But there is no other way, they are forced to register their own information and can only choose to leave their homes.

The officials tied everyone's hands behind their backs and connected them with a long rope, so everyone was tied to a rope. Although it is very troublesome, this method is extremely useful in order to prevent someone from escaping halfway. I believe that no one dares to escape, so the mighty migration begins.

It is difficult to move, including going to the toilet. They need to tell the officials around them: My Lord, please untie my hand. I need to go to the toilet. ? Then officials will untie their hands. After a long time, many people have simplified this language, so they can only say:? My Lord, I have to relieve myself. ? That's it? To relieve myself? The word was born, and people will say it later? To relieve myself? Officials directly understand that they want to go to the toilet. Although a person needs to untie a lot of talents to go to the toilet, no official dares to say that after all, someone who runs away will be more than one bargained for. Therefore, the toilet spent a lot of time along the way. Not only the people are hard, but also the accompanying officials are very tired.
