The National Flag of the PRC is a red rectangle emblazoned with five stars. The proportion of its length and height is 3 to 2. The upper left of the face of the Flag is studded with five yellow five-pointed stars. One of the stars is bigger than the others, with its circumcircle's diameter being three-tenth of the height of the Flag, and is placed in the left; the other four stars are smaller, with their circumcircle's diameter being one-tenth of the height of the Flag, encircling the big star on its right in the shape of an arch.
