Kang bed-stove

A kang bed-stove is a type of stove that is usually built into the beds in traditional homes in China. It is a stove that is placed at the foot of the bed and has a firebox below. But the heat from the firebox is distributed evenly throughout the bed. This makes sure that a person sleeping can stay warm even during the cold winter months.
