Stir in the hot water first. Mix for a while and then stir in the room-temperature water and cooking oil too. Grasp everything to form a ball, cover, and rest for 10 minutes. You don't need to knead the dough until very smooth at this stage because it may be hard to achieve. Just cover and let the flour and water combine.
After resting, then knead until very smooth (around 3-5 minutes ). Then divide the dough into 4 pieces. Shape each portion into a smooth round dough. Cover the rest for 20 to 30 minutes.
Assemble the pancake
Take one small ball out, and roll it out to a rectangle around 10cm wide and 8cm high. Brush some oil in the center part and then sprinkle Chinese five spice powder if using. Spread the chopped scallion in. Fold up the rectangle into a cylinder. Repeat to finish all four cylinders.
Take one out, slightly lengthening the cylinder with two hands, and then roll from one end to the other to form a snail shape. Suck the end into the dough.
Repeat to finish all four. Remember to cover to avoid drying out.
Then roll out the pancake into a large round circle. Be gentle and use your hand as most as possible. To get a perfect round pancake for beginners, get yourself a small pan (18 to 20cm in diameter) and push with your fingers to spread the dough over the pan.
Pan-frying
Pour around 2 tablespoon of oil in a pan and then place one pancake in.
Use middle fire to 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 twirl the circle from time and time especially the central part to ensure the circle is evenly fried. You can serve it as a whole or cut it into small pieces.
Mix all the seasonings for the dipping sauce. Serve along with the pancakes.

Notes
For a softer texture, add slightly more water.
If you need to add the amount, during the process of making the circle, do cover the rest of dough with a wet cloth so that the dough will not be too dry.
