Knead the dough thoroughly again and shape it into a ball. Dust some flour on a cutting board and flatten out the ball of dough. Keep flattening the dough with a rolling-pin. Then wrap the rolling-pin with the dough and roll to make the dough thinner.
After a while, unwrap the rolling-pin and dust some flour on the dough. Then wrap the rolling-pin again from the other direction and continue rolling. Keep doing this for more times in all directions until a thin circle of dough has been made. The dough should be about 1mm thick. One can roll more times to make it thinner or fewer times to make it thicker. The elderly and children may prefer thinner noodles.
