Soak red dates in water to treat old stomach trouble. Wash jujube and stir-fry with a frying spoon until the skin is slightly black. If it is not burnt, fry more at a time for later use. Break the fried jujube, put it in a cup and brew it with boiling water, three or four at a time, and add some sugar until the water turns yellow.
