Don't add angelica, it's already made up. 1) You should remove the core of the red dates first, and if it's dried longan, you should also remove the core. Both are made with cold boiled water first. 2) Boil red dates and longan water. Don't start a big fire, just a medium one. (Generally, I put two bowls of water (used to be a big rice bowl, but now the rice bowl is usually a medium rice bowl), eight red dates and ten longan. When the water reaches a bowl and a half, open the lid and put in the prepared eggs (eggs: take a bigger one, just break the shell and put it in the bowl without stirring), and gently put the eggs in the pot without stirring. 3) Wait until the whole egg is formed, then turn on a small fire to remove the foam from the soup. 4) Turn off the fire when the water reaches a bowl, and add brown sugar to the bowl. Note: Don't eat this when you have a cold or are angry.
