The Pavilion of Surging Waves is a classical garden made during the Sung Dynasty. Its name came from the poet Su Shunqin, who wrote that: 'If the water of the Tsang Lang river is clean, I wath the ribbons of my official hat in it; if it is dirty, I wash my feet'. The garden 'borrows' the nearby canal. Trees form a canopy above the garden and there are bamboos outside the windows, filtering the light and making it flicker.
