3. Drop some oil on your hand, coat each rough surface with oil, cover it with a wet towel or plastic wrap, and continue licking the surface;

4. Pick up a strip of dough cut with a knife. First, hold both ends with both hands, while gently pulling, while making the long noodles vibrate up and down. Finally, the dough sheet is thinned evenly. Put a long patch on the left wrist, and one end of the long patch is sandwiched between the thumb, forefinger and middle finger of the left hand, exposing a short section. Hold the exposed end of the patch with the thumb, forefinger and middle finger of the right hand and tear off a small piece. Then, the thumb, index finger and middle finger of the left hand send out a short patch, and then pull it with the right hand.
