First, establish the foundation. There is a rectangular hole in the middle, which is as high as two bricks. The base is also the foundation of the pot you mentioned, which is generally larger than the pot you bought, and the wind gourd is on the left or right (if your chimney is high or you burn firewood, you don't need the wind gourd).

Now you can build a pot wall to support the pot, and build holes to add coal or firewood in the front around. The bottom is thicker and bigger. When you put the pot in, it should not be too high from where you put the coal and firewood. The cost of coal and firewood is too high. After the pot is put away, it depends on whether it is flat or not. Finally, cement mortar can be used as a surface layer or a brick.
