Since most of the scenic spots in West Lake are free of charge, people come and go to Sudi every day, and Changdi has become a good place for citizens to exercise. If Sudi is finished, it may take a long time. It is suggested to ride a shared bicycle, which can save time and energy, as well as enjoy the beautiful scenery of the West Lake along the way. There are Yang Gong Dike and Su Dike beside the West Lake. The reason why Sudi is listed as the ten sceneries of West Lake is not only because of its long length, but also because of its high ornamental and recreational degree. Spring dawn of Sudi, whenever the spring wind blows, the willows and willows on the Sudi, the bright peaches burn, the long dike extends, and the Six Bridges fluctuate. So some poets praise Sudi like this - ""Keeping Qiantang to record Dasu, and taking it endlessly coincides with me. Changdi has a long name and will let Yiguang excel in this lake. "
