Introduction to the Nature Hall: The Nature Hall is one of the most important venues in the wetland exhibition area. The wetland covers an area of about 450 acres. It uses the Wujin regional symbol - "Three Cities and Three Rivers" of Yancheng in Spring and Autumn Period - as the prototype for landscaping. It combines the flowing water plank road and the infinite nature museum to guide tourists to get close to the wetland and achieve the integration of man and nature. . The "Mysterious Forest", Tropical Rainforest Pavilion, and Aquatic Plant Pavilion in the nature museum create a romantic and fairy tale-like ancient forest world by simulating various ecological environments. Visitors feel as if they have experienced a fantasy journey in the plant world.
