Another place that should be mentioned is the Liyushan mud volcano located on the boundary between Wantan and Hsinyuan. It spurts out bubbling hot mud at irregular intervals. The intriguing thing is that every such burst of volcanic activity always lasts exactly eight hours. The last time it happened was in April this year.
另外值得一提的景點，是位於萬丹與新園交界的鯉魚山泥火山，會不定時噴發滾熱泥漿，妙的是每次都固定噴發八小時，上次噴發時間是在今年農曆三月間。
