In fact, in the history books of China culture, there are quite a few words about toilets. Ouyang Xiu, a Song Dynasty man, said that his idea of reading was only realized on "three things": "pillow, horse and toilet". I think Mr. Zuiweng has many beautiful words, and all the famous writers' articles were born on the toilet. Everyone knows the story of "Luoyang paper is expensive", but I don't think it is clear about Zuo Si's writing Sandu Fu for ten years. According to the Book of Jin? 6? 1 Zuo Sichuan said: "(Zuo Si) After ten years of pregnancy, every family is writing a pen and paper, even if it is sparse." The "Francisco" mentioned here is the toilet. When Zuo Si wrote Sandu Fu, he put the pen and paper at the door, the court and the toilet, and wrote it down as soon as he had something. It can be seen that toilets and intellectuals are still quite predestined. A university professor said that books can be divided into two categories: books read on the desk and books read in the toilet. He also said that books that can be taken into the toilet must be good books, at least books that readers like to see. It seems that writers should not be arrogant, but should look at whether readers give you the courtesy of going to the toilet with books. That sounds reasonable.

The origin of the toilet should be unproven. I think, as soon as this human being got rid of animals, he began to choose a place to "export". This selected land, called toilet, should be beyond reproach. Thanks to our archaeologists, they discovered the origin of toilets in China. It was first discovered in the ruins of banpo village clan tribe in Xi 'an 5000 years ago. Archaeology found that the toilet at that time was just a pit. It can be seen that our "toilet civilization" has a long history.

From the Western Zhou Dynasty to the Spring and Autumn Period, nobles went to the toilet, temporarily found a slave to dig a hole, and then happily went to urinate. And once "a pit" is "abandoned", it will be filled by a slave. Moreover, it evolved relatively late. In ancient times, toilets were mostly placed around pigsty, so the view that toilets were "dirty" was passed down from generation to generation.
