1. Mix the dry yeast with warm water, add to the flour (according to the instructions) and knead thoroughly.
2, do meat stuffing: good pork belly mince stuffing, add salt, pepper, a little monosodium glutamate, chopped green onion, add a little water (add vegetables without water) and stir evenly, repeatedly, preferably in one direction, and then put it in the freezer for 30 minutes.
Note: How to add the vegetable stuffing: generally use vegetables (Chinese cabbage, Chinese cabbage and celery are also acceptable), boil a pot of water, add an appropriate amount of vegetables after boiling, remove them after discoloration, put them in a large pot of cold water next to them, cool them in time (otherwise the vegetables will turn yellow), and then remove them by hand, squeeze them dry, chop them up, squeeze them dry and mix with oil. Stir in the meat and mix well. Serve.
If you want spices, try them yourself and match them reasonably.
