Stir the dough with warm water for more than ten minutes, then divide the dough into several parts, roll it into small pieces with a radius of about 10 cm, sprinkle with salt, spiced powder and sesame oil, spread it evenly, cut it along the radius, fold it into a 90-degree fan shape, then roll it into a circle (remember to pinch the incision tightly, otherwise it will leak oil when rolling), and roll it into small pieces, the size and thickness depend on the individual.
