Soak the rice for an hour first, and wash the mugwort leaves in this hour. Boil Folium Artemisiae Argyi in a pot until slightly hard. Pick it up with a sieve and drop it with water. Then cut the mugwort leaves, and it will be better to cool them and wrap them up. After soaking rice for an hour, pick it up with a sieve and grind it by hand, or use a refiner. Think about water and rice twice when grinding. After the rice slurry is ground, put it into the pot. Add Ai and Bai to the fire, and it will slowly become a ball. Add a little salt to make balls, and then burn the bottom of the pot. At this time, put a little oil around the pot, so that it won't stick to the pot. Turn it over six times and you can cook it. It is also possible to make a small rice ball fruit like a steamed stuffed bun.
