Thinly slice the cabbage and sprinkle half a teaspoon of salt over. Let it sit for 10 minutes and then squeeze out all the water.
Mix the minced pork, salted cabbage, chives, soy sauce, ginger, and sesame oil together.
Place about a teaspoon of meat filling in the center of each dumpling and wet the edges of the dumpling wrapper with water to help it seal.
To wrap the dumplings start by folding the wrapper in half and then pinching shut one corner. Thereafter fold in the side of the dumpling wrapper closest to you to make a fold and pinch it closed. Continue to the end of the dumpling and then pinch it closed at the end.
Add some vegetable oil to a hot pan and fry for 2 to 3 minutes.
Add a ¼ cup of water to the pan and cover with a lid and let steam for another 4 minutes.
Remove the lid and let cook until the water has evaporated for about one to two minutes.
Serve with Chinese black vinegar as dipping sauce.
