Famous spring introduction: Dalongtan is the most famous scenic spot in the park. Emperor Qianlong also praised it in his "Xinxingzhou Chronicle". There are 7 spring holes at the bottom of this pool. Clear springs gush out and there are sunken stone bridges under the water, which are faintly visible. The mottled tree shadows beside the pool are clearly and picturesquely reflected in the pool. The breeze blows, the ripples are gentle, the tree shadows are scattered, and the fish are swaying, which is very interesting.
