Combine the sauces in a small bowl. In my opinion it should be tangy with just a hint of sweetness, but you can adjust it to your tastes.
Heat up the oil in the wok and sauté the garlic until slightly brown at the edges. Then add the beef and cook until the exposed sides of the meat are sealed.
Shift the beef to one side of the wok by tilting it, then add more oil and crack in the egg. Using your spatula, scrape the sides of the wok and mix the egg so that it scrambles.
Add in the half packet of noodles and the sauce. Toss everything around until the sauce coats all the noodles.
Add the Chinese broccoli, and cook for 4-5 minutes or until the greens are wilted. Finally, serve it straight out of the wok!
