Introduction to Zuiweiting and Chi: Zuiwei refers to Zhang Xu, a famous calligrapher in the Tang Dynasty. He was good at cursive calligraphy and was known as the "Cao Sage". Zhang Xu once served as a county captain in Changshu and was addicted to alcohol, so his old location was called "Zuiwei Street". There is a Zuiwei Pavilion and a "Zuiwei Pond" built in the Fangta Garden separated by a wall from "Zuiwei Street" to commemorate the important position of "Cao Sheng" in the history of Chinese calligraphy.
