Marinating and massaging pork with cooking wine and potato starch for about 10 minutes.
Fill a pot with lightly salted water and bring to a rolling boil over high heat. Cook the dry lo mein noodle in the boiling water for about 3 minutes, stir occasionally, rinse under cold water and drain well. Set aside.
Toss the dark soy sauce and oyster sauce onto the noodle and mix well.
Blanch the prepared bok choy and set aside. (Link for how to blanch vegetables)
Heat oil in a pan over medium-high heat, add garlic and stir fry for about 1-2 minutes or until fragrant and browned.
Stir in the pork and stir fry for about 2 minutes or until the pork has changed color.
Stir in the lo mein noodles and continue to stir fry for another 3 minutes. (I used a long chopstick when stir fry the noodles to avoid burning)
Add in the blanched bok choy and stir fry for about 1 minute.
Top with chopped green onion and serve.
Notes
Marinate the pork with cooking wine and potato starch before cooking would help reduce the blood smell of the meat and maintain its tenderness when cooking.
