Boil the quail eggs and peel the shells.
Cut the beef into bite-sized pieces.
Add the beef and water to a pot and bring to a boil.
Once the beef is cooked, add the quail eggs.
Add soy sauce, sugar, cooking wine, and minced garlic, and simmer over medium heat.
When the braising sauce is reduced by half, add spicy chili peppers and onion, and simmer a bit more.
Transfer to a bowl and serve.
