Santan Yinyue is one of the ten scenic spots of West Lake, known as "the first victory of West Lake". After Su Shi dredged the West Lake, in order to show the lake mud silting again, three bottle-shaped stone towers were erected in the three deepest depths of the lake outside the embankment to mark the strange scenery of "the lake has a deep pool, the bright moon is watery, the stone tower is photographed, and the moon is full in 18 months". The back of the fifth set of RMB one-yuan notes adopts the scenery of Santan Yinyue.
