Speaking of toilets, their status can be said to be very high nowadays, almost essential for every household. So the question is, how were toilets born? In fact, the predecessor of the toilet was Huzi, also known as the Night Pot. The reason for changing its name was because the grandfather of the founding emperor of the Tang Dynasty, Li Yuan, was named Li Hu, so "Huzi" was renamed "Mazi". Later, due to various needs of people, the horse shaped toilet also changed into a barrel shape, and thus the "toilet" was born. To be honest, I am quite interested in the inventor of the night pot. Do you know who invented the night pot, readers?
