Yishuituolan is an extremely rare natural phenomenon in Linyi, east China's Shandong Province. According to Yizhou Chorography, this phenomenon appears in the east of Linyi City. After the confluence of Yihe River, Benghe River and Suhe River, pure and turbid streams coexist in the same water area. It seems like that Yishui (water converged by Yihe River, Benghe River and Suhe River) drags a cerulean silk ribbon.
