霤神 The spirit of the eaves. A work entitled 獨斷 Tuh-twan says, " In the last month of summer 土氣 the subtile qualities of the ground begin to be vigorous, and sacrifices should be offered to the central roof, and to 霤神 the spirit of the eaves, in the house. When sacrifices are offered to the central roof, the table should be set up under the window."
