The Book of Rites recorded people's habit of washing their hair and bathing regularly at that time, and the internal regulations put forward the requirement of "taking a bath for three days and taking a bath for five days", that is to say, washing their hair once every three days, and simply taking a bath with a ladle of water. They must take a bath every five days and wash their whole bodies. It is also stipulated that the upper and lower bodies should be dried with two towels respectively. Under the conditions at that time, they were very sanitary.
Bathing is not only for cleaning hair and body, but also a kind of etiquette. For example, in ancient times, it took three days to show piety when worshipping ancestors, and when going to court, you should also take a bath to show respect, as we say now, dressing up is respect for others. In ancient times, bathing was also an important expression.
In addition, as early as the Spring and Autumn Period, it was stipulated that if someone died, they should never be buried hastily. It is necessary to clean up the body of the deceased, cut off fingernails and toenails, and put on clean clothes before the funeral can be held. This custom has also been passed down to the present. People live all their lives, to be clean, to be clean, and to be clean again. This is China's simplest view of life and death.
The ancients were also very particular about bath utensils. Ordinary people use wooden barrels, while rich people use baths. The palace can introduce hot springs and running water, add petal spices, take a comfortable bath, and have servant service and massage to relax, which is much more enjoyable than we do now. For example, Yang Guifei's Huaqing Pool, and now we can still see the remains. Presumably, Yang Guifei also spent many wonderful days in this pool!
