Who invented the toilet?

To talk about the history of toilets, we have to start from the Han Dynasty. According to Xijing Miscellanies, the court of the Han Dynasty made "tigers" out of jade, which were held by the attendants of the emperor for his convenience at any time. This kind of "tiger" is a special appliance called toilet and urinal by later generations, which is also the predecessor of toilet. According to this, it is said that this kind of "nothing" was also invented by the high-impedance Liu Bang who used the crown of Confucian scholars as a drowning device. There is another saying about the invention of "nothing", which is also said to be related to the emperor. According to legend, in the Western Han Dynasty, Li Guang, a flying general, shot and killed a crouching tiger, which made people cast a copper drowning device in the shape of a tiger and put urine in it to show contempt for the tiger. This is the origin of the name "Tiger". However, when the Emperor of the Tang Dynasty sat in the Dragon Pavilion, the disrespectful term was changed to "beast" or "girl" because one of their ancestors was called "Li Hu", and later it was commonly known as "toilet" and "urinal". There is also a joke among them. Zhao Kuangyin, Song Taizu pacified Sichuan, and transported all the objects in the palace of Houshu back to Bianjing. He found that there was a basin inlaid with agate and jade, which was so happy that it was almost used to hold wine. Later, Mrs. Hua Rui, the favorite princess of Shu Yu Chang, was called to dedicate herself. When Mrs. Hua Rui saw that this thing was offered by the Emperor of the Song Dynasty in several cases, she quickly said that it was my husband's urinal! Surprised Zhao Kuangyin's strange call: "How can there be a reason not to perish the country by using this kind of urinal?" Smash this baby right away. The first detailed written record of the toilet was the wooden horse in Ouyang Xiu's Return to the Field II in the Northern Song Dynasty, and it was interpreted as a wooden toilet in Ci Yuan. The toilet used by the people in ancient China is a round wooden barrel with a lid, which is smeared with tung oil or fine waterproof vermicelli. Who invented the toilet, even many experts can't tell. One theory is that John Harington, a British aristocrat, invented the first practical toilet in 15 96-a wooden seat with a water tank and a flushing valve. Before that, many people always went to the nearest big tree and river to solve it on the spot. Although Harrington invented the toilet, it was not widely used because of the imperfect sewage system. In 1861, Thomas Kleppa, a British plumber, invented an advanced water-saving flushing system, and waste discharge began to enter the modernization period.
