Soak the rice noodles in hot water for about 30 minutes until soft.
Drain and rinse the noodles under cold water to prevent sticking.
Heat the vegetable oil in a large pan or wok over medium heat.
Add garlic and sauté until fragrant, about 30 seconds.
Stir in the sliced chicken (or tofu) and cook until browned.
Add the Chinese broccoli and stir-fry for 2-3 minutes.
Push the mixture to one side of the pan and crack the eggs on the other side.
Scramble the eggs until cooked, then mix them into the chicken and vegetables.
Add the soaked noodles, soy sauce, oyster sauce, and sugar. Toss to combine.
Stir-fry everything together for another 2-3 minutes until heated through.
