Dayu Haitang Square is an important part of Jianghao Park, located from Xianglong Riverside Community to Shijiayan Wharf, covering an area of about 6,543,800 square meters. It is designed with edge pools, three landscape pools and many rest facilities.

The design of Big Fish Begonia Square was inspired by the national animated film Big Fish Begonia. The three landscape pools in the square are three local classic pictures, and the flood control retaining wall corresponding to the square will be a 3D painting of the big fish begonia. This paper introduces the characters' scenes and stories taken from Shan Hai Jing and Xiaoyao Tour through the Chinese style of movies.
