Take out a small pot (don't use a large one). Then pour-in 1 Cup of beef broth.
Season with Soy Sauce (2.5 Tablespoons) and Sugar (1 Tablespoon).
Dice one whole onion into thin strips. Add the onion slices into the pot.
Next, add the blanched beef pieces back into the pot.
Bring the pot up to a boil now.
While you wait for the pot to boil, crack two eggs into a bowl. Whisk it thoroughly.
Once the pot comes to a boil, simmer on MEDIUM heat for 3 minutes.
After 3 minutes, raise the heat to a HIGH.
The pot should be vigorously boiling. Then gently add the beaten eggs in a circular motion into the pot.
