The best places to visit in Yiyang in one day

I know the best places to visit in Yiyang for a day trip are as follows:

Anhua Longquan Cave, Yiyang Royal Lake Ecological Tourism Zone and Yiyang City Museum. Anhua Longquan Cave is a representative tourist attraction in Yiyang and has the longest goose pipe in the world. Yiyang Royal Lake Ecological Tourism Zone is one of the top ten freshwater lakes in Hunan. It has a beautiful environment, lush vegetation and fresh and natural air. Yiyang City Museum is large in scale and has complete functional facilities. It displays ancient rare treasures, modern celebrity deeds and historical materials, as well as exquisite bamboo crafts.
