Place ground pork, Chinese chives, ginger, salt, pepper, soy sauce, rice wine, sesame oil, cornstarch and egg whites in large bowl. Stir to combine.
Place 2/3 tablespoon of the mixture in the center of a wrapper. Line the edge of the wrapper with a little water. Fold wrapper in half, pressing to remove any air pockets. Crimp edges, pressing them to seal. Place pot stickers upright on the countertop, pressing slightly to create a flat bottom. Repeat steps with remaining wrappers.
To fry the pot stickers, heat oil in 12-inch nonstick skillet over medium-high heat. Place wrappers, flat side down, in the pan in a clockwise spiral (or flower) shape, working around the edge of the pan, then filling in the center. They should fit tightly in the pan.
Allow pot stickers to cook 2 to 3 minutes or until bottom is just golden brown. Holding a lid over the pan to avoid splattering, add 1/3 cup of water. Set lid on top of pan, offsetting it to allow steam to escape. Cook until water evaporates, about 6 minutes. Remove lid from pan and cook until bottoms are crisp and golden.
To ensure pot stickers stay together in their flower shape, stir together the frying mixture (water, cornstarch and vinegar). Using a small spoon, pour a little of the mixture into the crevasses between the individual pot stickers. Shake pan gently to prevent sticking. Cook for 1 minute, then remove from heat.
Carefully turn a plate that is larger than the pan upside down over pot stickers. Flip pan onto the upside down plate so the pot stickers are crispy side up on the plate in their flower formation.
