1. Cut the tofu into small pieces the size of a small fingernail. 2. Cut the fat with skin into small pieces that are consistent with the size of the tofu. Of course, if you like to eat meat skin, you can also buy some meat skin separately and cut it into small pieces of the same size. 3. Stir-fry the cut fat meat and meat skin in a pan to fry out the fat, then take out the stir-fried meat skin and meat cubes and set aside. Note: Don’t stir-fry it too dry, there is still a little fat in the bun and it’s delicious! 4. After draining the water from the cut tofu cubes, pour it into the oil that was stir-fried just now and stir-fry until the tofu is slightly yellow, stir-fry the water until it dries up and set aside for later use. 5. Chop the lean meat into fillings, chop the leeks, add the stir-fried tofu cubes, pork skin, fat pork cubes, onions, ginger, winter vegetables and all the seasonings and mix them into steamed bun fillings. 6. Knead the noodles.

Make the buns 7. After the water boils, steam it for 15 minutes, then turn off the heat and let it warm for a few more minutes and it’s ready!
