This is a popular classic in the Chinese restaurant scene. You can replace the pork with chicken or shrimp, but the original recipe is with pork. My parents say this recipe tastes better than the ones they've had in Canadian Chinese restaurants. Once you get the hang of making it, you'll want to make it often. If you don't want to spend the time making pancakes, you can use soft tortillas to replace. The homemade pancakes are much better though. This dish goes well with hot and sour soup, for a Beijing style meal.
