Have I misunderstood the cooking method? It's simple. Slice wax gourd, pumpkin and loofah and stir fry. Add some oil and salt. If you eat Chili, add some green pepper and garlic. Bitter gourd often copies eggs or pork, but remember to stir-fry everything in the hot pot now, take it out, pour out the bitter water, and then stir-fry normally. I wonder if it will help you.
