Methods A paper tube was made of hard paper roll, with the front as thin as a cone and the back as thick as a cone. The front eye is about 4-5 mm long and 5-7 cm long. Hold the paper tube with your hand, insert it into the edge of your ear, find someone else to hold the moxa stick, lie with your ear slightly away from the bed, and let the smoke of the moxa stick slowly enter your ear.
