The dwarf wall (kan qiang) acts as a structural support

The dwarf wall (kan qiang) acts as a structural support for window sills and enhances the stability of the overall structure. Traditionally, dwarf walls were constructed using compressed earth bricks laid flat to reach the desired height. However, glazed bricks were later utilized in palace buildings to signify their high status.

Dwarf walls were one of the first elements visitors would encounter upon entering a compound. As a result, in palaces, they were often adorned with intricate designs or glazed bricks to project grandeur and opulence.
