The Chinese symbol commonly found on the roof of Chinese houses is known as the "dou-gong" (斗拱) system. It is not a single symbol but rather a structural element in traditional Chinese architecture.
The dou-gong system consists of a series of interlocking wooden brackets that support the weight of the roof and transfer it to the columns below. These brackets are typically arranged in a tiered fashion, resembling a set of brackets stacked on top of each other.
The dou-gong system is not only functional but also carries symbolic meaning in Chinese culture. It represents the traditional craftsmanship, architectural wisdom, and the harmony between humans and nature. The interlocking brackets symbolize the unity and cooperation of different elements, reflecting the Chinese philosophy of balance and harmony.
The dou-gong system has been used in Chinese architecture for centuries and is considered a distinctive feature of traditional Chinese buildings, such as temples, palaces, and ancestral halls. Its intricate design and cultural significance make it an important symbol of Chinese architectural heritage.
