Yang Public Causeway, also known as Yang Gong Di, is a scenic area located in the western part of Hangzhou, Zhejiang Province, China. Spanning across West Lake, it is a popular destination for both domestic and international tourists. The causeway connects several scenic spots including Su Causeway, Bai Causeway, and Leifeng Pagoda.

The name "Yang Public Causeway" originates from a historical figure named Yang Shi, who was a scholar during the Song Dynasty. According to legend, Yang Shi was so devoted to learning that he would travel great distances to seek knowledge from renowned scholars. One of his notable encounters was with the famous philosopher Cheng Yi at his residence on West Lake. The story goes that Yang Shi arrived at Cheng Yi's home during a heavy snowfall and waited outside the door for hours before finally being granted an audience. This event has been immortalized in Chinese literature and art as an example of dedication and respect for learning.

Yang Public Causeway itself is approximately 2.3 kilometers long and runs parallel to the lake. It is lined with lush trees and flowers, providing a picturesque setting for visitors to enjoy the natural beauty of West Lake. Along the causeway, one can find various pavilions and scenic spots such as Xiangshan Pavilion and Yushan Pavilion, which offer beautiful views of the lake and surrounding landscapes.

The causeway also serves as a recreational area where locals and tourists can engage in activities such as cycling, walking, or simply relaxing while enjoying the serene environment. It is particularly popular during spring when the cherry blossoms bloom along its length, attracting visitors from all over.

In summary, Yang Public Causeway is not only a significant cultural landmark but also an essential part of Hangzhou's tourism industry. Its historical significance combined with its natural beauty makes it a must-visit destination for anyone exploring West Lake or Hangzhou city.
