Slice the pork first into long, thin strips around ½ cm in width, then cut into 3cm pieces. Combine the pork with the marinade ingredients.

Heat a wok over a high heat until very hot, then add 2 tablespoons of oil. Add the pork and spread it into a single layer. Let it sit  in the wok without stirring for about 2 minutes, until one side of the pork is browned, then toss and cook for another minute or two until the pork is barely cooked through. Remove from the wok and set aside. 

Return the wok to the heat and add the remaining tablespoon of oil. Add the onion and garlic and toss for about a minute until fragrant. Add the celery and toss for another 2 minutes, until the celery is cooked. Return the pork to the wok with any juices collected and add the oyster sauce, Shaoxing wine and about ¼ cup of water (you could use stock, if you prefer). Toss to combine, then add a little of the cornstarch mixture, tossing until the dish thickens. Add a little more of the cornstarch mixture if the sauce for the dish looks too thin. It should be thick enough to coat the meat and vegetables in the wok. Serve with rice.
