Located in Linyi County. Personally feel better in winter. There are some ancient stone monuments inside. It seems to be a local Ming Dynasty or a poet in what era. The park is not too big, but the lake water temperature is kept at about 20 degrees all year round, almost becoming a hot spring. It is said that the lake is also connected to the East China Sea. It is necessary to eat Linyi whole sheep in the local area. It is very authentic and black goats.
