Practice: 1. First, cut all the ingredients into filaments for later use, and stir the eggs evenly. 2. Boil the broth, add black fungus, lactone tofu, shredded winter bamboo shoots, salt, pepper and soy sauce to boil (meat dishes are put in this step). Many people like vegetarian food, so I didn't put any meat dishes. 3. Beat the starch into water starch, and then put it into the cooked soup and stir well. 4. Boil the soup again, add the egg liquid, stir while pouring, put it into a bowl after boiling, add vinegar, stir well, and pour in a proper amount of Chili oil, sesame oil and coriander to serve.
