So in ancient times, when living conditions were relatively backward, how did people keep out the cold in the slight cold season? Let me introduce you.

Carbon fire heating

In primitive society, our ancestors began to use fire to keep warm. Later, the fire was put into the baked pottery and could be moved around. During the Qin and Han dynasties, it was mainly heated by fireplaces and fire walls. The fire wall is made of two tiles locked together to make a tube, which is wrapped in the wall and communicated with the furnace for heating. The Eastern Han Dynasty's "Xijing Fu" contains: the court inherited the east and Wen Yanbei. Speaking of greenhouses.

"The Legacy of Kaiyuan Tianbao" describes the scene of the palace heating in the Tang Dynasty: there are hundreds of pieces of charcoal in the west, each of which is more than a foot long. Its charcoal is blue and hard as iron, so it is called Ruitan. Burning in the furnace, there is light but no flame. Each one can burn for ten days, and its heat is too strong to approach.

This kind of clothing not only has a luxurious appearance, but also has a warm effect.
