One: Fire box: There are two kinds of fire boxes, one is the old-fashioned fire box with charcoal as the main material, and the other is the electric fire box used in general movies now. Since the old charcoal fire box is basically not used now, I won't introduce it. I mainly introduce the electric fire box.
Two: brazier is to use an iron basin, put charcoal in it, and then burn it. Everyone can keep warm around the brazier. This method of warming fire is very simple. Just take an iron basin and put charcoal in it. When heating, put your hand out on the brazier and you can bake it. Some carpenters also make a low wooden frame to fix the brazier. With this wooden frame, it is more convenient, because you can put your feet on the wooden frame to keep warm together, which is very comfortable.
