3. Drain the soup pot, put enough water at a time, leave room for evaporation, and don't add water in the middle of cooking.

4. Put the tremella and rock sugar (about 3: 2) into cold water, and bring it to a boil. Always stir the pot to prevent the tremella from sticking to the pot. After boiling, turn down the heat and cook, and perhaps stir the pot constantly.

5. Boil the soaked coix seed and lotus seed for about half an hour, then pour in lily, red dates, medlar and codonopsis pilosula and continue to stew for half an hour until the tremella is gelatinized and the soup is sticky.
