Lake of wash medicine is located on the main peak of Meiling Luohanling, covering an area of more than ten mu. It is rumored that Li Shizhen, a great medical scientist in the Ming Dynasty, led his disciples to come here to pick medicine and wash medicine, so this is called the medicine lake. There is also a folk legend that one of the "eight immortals", Tieguai Li, washed his feet here, so the locals called her "foot-washing dock". The pleasant scenery around the lake is a great place to escape the summer heat.
