Simple secret: buy a piece of bamboo chicken in the market, buy it in the American ginseng drugstore, add salt to the boiled water, monosodium glutamate, chicken powder sugar, carved wine and a little soy sauce to color it. This is soup. Find a big thing, put chicken, ginseng, a few slices of ginger, red dates, longan pulp and medlar together, and pour in the prepared water. Cover with plastic wrap or seal, and steam for two or three hours.
