Place the sliced pork in a bowl. Add the grated ginger, a tablespoonful of soy sauce, a drizzle of rice wine, a tablespoonful of starch and a drizzle of sesame seed oil. Mix well. Set aside.
Drain the black fungus and cut into one-inch slices.
Cut the cucumber vertically into halves. Scoop out and discard the seeds. Cut the cucumber halves into slices about a quarter of an inch thick.
Crush, peel and mince the garlic.
In a small bowl, make the sauce by mixing together the oyster sauce, sugar, meat broth, a tablespoonful of starch and a tablespoonful of light soy sauce.
Heat a tablespoon of oil in a wok or frying pan. Drizzle in a little soy sauce over the beaten eggs and whisk. Pour into the hot oil. When partially set, stir around to break into rather large lumps. Scoop out and transfer to a plate.
Pour the rest of the cooking oil into the pan. When starting to smoke, spread the marinated pork in a single layer. Do not move them for a minute or so until the undersides are browned. Flip over and brown the opposite side.
Add the garlic and scallions to the pork. Stir fry for a minute.
Add the sliced black fungus, cucumber and eggs to the pork. Stir fry for half a minute.
