It was difficult to get up to the water-boiling sheds. “I allow three kinds of stairs: stairs of brick, stone, and wood.” People fell down while climbing the stairs. “I allow rails.” The water-boiling sheds didn’t have doors. “I allow doors, door frames, lower hinges, upper hinges, door jambs, bolt sockets, bolts, latches, keyholes, door-pulling holes, and door-pulling ropes.” Grass and dust fell into the water-boiling sheds. “I allow you to firm up the structure and then to plaster it inside and outside, including: treating with white color, black color, and red ocher; making garland patterns, creeper patterns, shark-teeth patterns, and the fivefold pattern; putting up bamboo robe racks and clotheslines.”
