Prepare a large mixing bowl. Mix Salt (1/2 teaspoon) with All-Purpose Flour (2 cup).
Dig a small hole in center and then pour the Water (1/2 cup) in.
Wait for 10 minutes and then stir in the cold Water (1/3 cup) and Vegetable Oil (1 tablespoon).
Grasp everything to form a ball, cover and rest for 5 minutes and then knead until very smooth (around 3-5 minutes ). The dough should be quite soft.
Cover the rest for 20 to 30 minutes.
While the dough rests, thinly slice the green part of the Scallion (2 cup).
After resting, the dough should be quite easy to roll out. Divide the large dough into 4 pieces and roll each piece into a large around circle.
Brush some oil, sprinkle Chinese Five Spice Powder (1/2 tablespoon), and chopped scallion (leave the 1 cm of the edge empty).
Roll up the circle into a cylinder. And further roll into the shape of a snail.
Roll out the snail into a thin circle.
Brush some Cooking Oil (1 tablespoon) on the pan and move the pancake into the pan. On medium heat, pan-fry until the surface becomes brown around 2-3 minutes. And turn over to fry for another 1 to 2 minutes. Use a spatula to press the circle from time and time especially the central part to ensure the circle is evenly fried.
Remove the circle out and cut into wedges.
