Bring a large pot of water to a boiling and cook the noodles for 1 minute. During the process, separate the noodles. Transfer the noodles out and drain.
Add around 2 tablespoon of oil in wok and slow down the fire, fry until the noodles becomes dry and crispy. However this is only optional if you want a real Cantonese flavor. You can skip this to make a regular chow mein recipe. Transfer the noodles out.
Turn up the fire and add another tablespoon of oil, add onion and the white sections of green onions in.
Place noodles back, add blanched chive, spring onions and drizzle the sauce. Mix well. Sprinkle some salt if necessary. Serve immediately.
