Introduction to Henan Garden: The Henan Exhibition Garden closely focuses on the design concept of "harmony between man and nature" of the famous painting "Along the River During the Qingming Festival" by the famous Northern Song Dynasty painter Zhang Zeduan, and restores the Hongqiao fragment, the core part of the picture. The garden landscape is the main line, and the "picture within a picture" is used to construct a "view within a scene" and a "garden within a garden" through geographical crossing, which truly reproduces the prosperous scene on both sides of the Bianhe River during the heyday of the Northern Song Dynasty thousands of years ago.
