The supporting arch is a whole piece of wood installed between eaves and beams, supporting the bearing force between the cantilever of building and purlin. This pair of supporting arches take lions as their theme, which implies high officials in traditional Chinese culture. The mother lion and four small lions are playing— a vivid and happy scene. The elaborate lion carving is of the Qing dynasty style. In Huizhou architecture, there are a lot of lion images, a very common theme among the "three sculptures". Huizhou people were used to expressing their pursuit with architectural composition and homophones. For them, the lion had three meanings.

Firstly, “lion” was pronounced the same as the official positions of "Tai shi" and "Shao shi" in ancient times, therefore, it is an expression of Huizhou people’s yearning for promotion to high ranks. Secondly, the sound of "lion" is the same as "thing", expressing their expectation that "Everything goes as you wish." Thirdly, the lion is a powerful beast that drives away evil spirits. It is peaceful and dignified, showing majestic force and auspicious atmosphere.
