The earliest establishment of public toilets can be traced back to the Xia Shang period. Let's take a look at it.
1, in fact, as early as the slave period, we already have the concept of toilets. In the Xia Shang period, in fact, there was already a prototype of a public toilet. For the ancients, we have always thought that their lives were relatively rough, so why build public toilets? For the sake of the beauty of the city, in fact, it is not.
2. The public toilets in the beginning were actually to prevent the occurrence of plague. So why do toilets solve this problem so well? If there were no toilets at that time, then everyone would be defecating on the ground, and a poor sanitary environment would cause infection, and if it was severe, it would cause plague. In ancient times, there was nothing people could do about the plague.
3. At this time, some people will ask, how do they solve physiological problems when marching and fighting? Defecating in place? Not really. These sergeants would dig a large pit away from the kitchen and sleeping place, and basically the sergeant would solve it here, which is a simple public toilet. Before the sergeants left, they would bury the public toilets they had built to avoid spreading the plague.
