Common errors include over‑cooking the scallion whites, burning the greens, using too much soy sauce which makes the dish overly salty, and not tossing the noodles quickly enough, which can cause them to become soggy.

Light soy sauce provides salty seasoning while dark soy sauce adds a deep amber color and a subtle caramelized flavor, creating a balanced taste and appealing appearance.
