Ancient people wiped their bottoms with bamboo chips?

Ancient people wiped their bottoms with bamboo chips. Toilet cover, also known as post-it notes and excrement stirring sticks, refers to wooden strips or bamboo strips used to wipe dirt after defecation. This toilet seat was still used in parts of China and Japan in the last century. This is recorded in Zi Tongzhi Bamboo Slips and Fa Zhu Yuan Lin. In addition to archaeological evidence, the use records of toilets in the Tang and Song Dynasties are also found in historical books. Song Maling's Biography of Southern Tang Dynasty: "The former teacher and Zhou Zhou wore monk's hats, robes, recited Buddhist scriptures and bowed down, which was a tumor. Cut off the monk's toilet strip by hand, try it on the cheek, and make it up when the thorn is less. " According to Ji Tang's Forty-Seven Notes of Zi Tong Zhi Jian, Han Kun was appointed as our ambassador to Zhenhai, and delivered a lot of materials to Guanzhong, including a toilet fund: "Then put the equipment on the boat, go down to the toilet fund, write all the notes and everything is ready."
