Boil the eggs for 10 minutes; after 10 minutes, let them rest in cold water.
In a pot, add in soy sauce, dark soy sauce, water, garlic, tea bags, cinnamon stick, bay leaf, star anise, and sugar. Bring it to a simmer and let it boil for 5 minutes.
Using the back of the spoon, lightly crack the egg. You want to break enough so the broth will go into the egg and not too much, so the shell falls off. Make tiny cracks all over the egg.
After 5 minutes, turn the heat down to low and add in the eggs. Depending on how big your pot is, you want to make sure all the eggs are in the sauce. If not all the egg is in the sauce, add in more water. Put the lid on and let it simmer for 1 hour.
After 1 hour, you are ready to eat! You can also let it simmer for longer or turn the heat off and let it marinate overnight.
