In the Tang Dynasty, Li Bai's "Sleepwalking One Day" has a sentence "Xie, climb the blue ladder" on his feet. In ancient times, people were very particular about sending shoes, and only clogs for changing clothes were used by overnight guests.
In his other "Yue Nv Ci", there is a sentence "My feet are like frost, I don't need crow's head socks." The popularity of poetry is not as high as others, but it is enough to prove that there were slippers in ancient times, but the name of the heel in those days was different from now, and ancient women rarely went out, so there were few records of washing shoes. Of course, Li Bai is also a god. He can walk around in slippers without losing his image.
Like Ye Shaoweng in the Song Dynasty, there is also a saying that "I cherish my fangs and seal the pale platform". The fangs here are the teeth on the clogs, which are used to prevent slipping, and are also used by slipper owners to visit friends. This kind of clogs was very popular in the Song Dynasty, and it was also widely used by literati, so there was such a song "Going to the garden is not worth it".
There were not many toiletries in ancient times, and clogs were widely used. After all, clogs can be worn in a humid environment, so that shoes will not be mixed up in a bathing environment. As for work, it would be disappointing not to say anything. If we put them on now, some of them may fall off, but people were wearing such shoes then.
Generally speaking, there were slippers in ancient times, and clogs, as slippers, have been passed down from the Han Dynasty to the present.
