The various kinds of bridges can be said to have myriad forms and postures. In Chinese gardens, there are slab bridges made of stone, wooden bridges, stone arch bridges, multi-hole bridges, covered bridges, and pavilion bridges. Bridges placed in gardens serve not only practical purposes but also functions such as appreciation, touring, and dividing garden spaces. In the gardens of places like Hangzhou, there are also bridges from historical stories and legends, such as the Broken Bridge on the Bai Causeway in the West Lake. The bridges in gardens often attract many tourists with their robust and delicate postures resembling flying rainbows, or their small and changeable, exquisite and meticulous structures.
