Decorations and reliefs on the capitals, pediments, eaves and window frames are a testament to imagination and delicate workmanship, and range from traditional auspicious motifs, angels and badges, to anything people might see in life such as swallows, bitter gourds or even trains.

However, the traditional Chinese interiors are a sharp contrast. Inside, the buildings usually have a rectangular, circular or octagonal tianjing (patio) enclosed by wooden balustrades.

This layout not only improved lighting, but also made it easier to deliver messages and move goods, given that while the ground floor was usually given over to shops, the upper floors often served as warehouses and residences.

As one of those who grew up in the neighborhood, 69-year-old Cai says the design and craftsmanship of these historical buildings reflect local open-mindedness and diligence, pragmatic commercial acumen, emphasis on traditional culture and moral values, and maybe, a penchant for the elaborate display of wealth.
