What are the characteristics of architectural style in Guangxi?

Guangxi's national architecture has its own style. Among them, the "Gan Lan" building of Zhuang nationality is an important part of China's ancient architectural heritage, which has developed into one of the main living forms of all ethnic groups in the south. Dong people have high building skills, especially the Drum Tower and Yufeng Bridge. Bridges and drum towers don't need a nail, but they are just cut through countless ethnic buildings with different styles in Guangxi.

Bridges and drum towers don't need a nail, but countless holes of different sizes are drilled on the pillars to connect them. They wear straight sleeves obliquely, criss-crossing, with precise structure and firmness that can be extended for 200 to 300 years without loss. This is a major feature of nail structure.
