1, the toilet is also called a toilet, which is a covered bucket for defecation. The invention of the toilet is called a great invention, which solved the problem of people eating and drinking Lazar. Later, it evolved into a toilet using siphon, spiral siphon, and now the latest jet siphon and super spiral siphon. Some people think that the toilet is the root of all evil, because it consumes a lot of domestic water. There are many kinds of toilets, including split toilets and conjoined toilets. With the development of science and technology, many novel varieties have appeared.
According to the collocation method of toilet cover, it can also be divided into ordinary toilet and smart toilet. Smart toilets can be divided into automatic changing sets of smart toilets and non-automatic changing sets of smart toilets. The former includes automatic sleeve changing and water washing, and automatic sleeve changing with water washing and drying. The history of toilets can be traced back to the Han Dynasty. At that time, the toilet was called nothing, which was dedicated to the emperor. Legend has it that it is made of jade. It was held by eunuchs who served the emperor specially for the convenience of the emperor at any time. Later, in the Tang Dynasty, because there was a man named Li Hu in the royal family, he changed his name to Beast or Maiden in order to avoid taboo. Later, in the circulation, it evolved into the name of the toilet.
2. A brief history of toilets
The ancient stone toilet "Miscellanies of Xijing" said that the court of the Han Dynasty made a "tiger" out of jade, which was held by the emperor's attendants for the convenience of the emperor at any time. This kind of "nothing" is a special appliance called toilet and urinal by later generations, and it is also the predecessor of toilet. It is said that this kind of "nothing" was also invented by great-grandfather Liu Bang with the crown of Confucian scholars as a drowning device.
There is another saying about the invention of "nothing", which is also related to the emperor. It is said that Li Guang, a flying general in the Western Han Dynasty, shot and killed a crouching tiger, which made people cast a copper drowning device in the shape of a tiger and urinated in it to show their contempt for the tiger. This is the origin of the name "tiger". The Emperor of the Tang Dynasty changed this disrespectful address to "beast" or "girl" because one of his ancestors was called "Li Hu", which was later commonly known as "toilet" and "urinal".
