This garden of Suzhou is the oldest one among those, which are preserved to this day and occupies an area of 1.1 hectares. In the North Song Dynasty (1044 A.D.) the poet Su Shunqin was demoted and forced to move to Suzhou . For enjoying the clearness and quietness of the water-surrounded high place, he purchased it at a price of 40,000 qian and built a pavilion by the water. The name of the pavilion is taken from the lyric “Be the surging wave clean, it washes my hat. Be the surging wave dirty, it washes my feet.”
