Radish is sliced or diced, just remember not to peel it. In an iron pot, add cold water, boil the cold water, and add chopped radish. Don't put too much water, usually put about 4 bowls of water, and finally cook to a bowl. Finally, just have a bowl. Boil in boiling water for more than 15 minutes. You can boil in white water without putting anything.
After cooking, put it away when the water is slightly cold, and drink soup with water, mainly boiled water. Radish is the best. If you don't like it, it doesn't matter if you just drink water and don't eat radish.
