First, read the English article below.

If you want to be absolutely precise, get a mathematical compass and attach a pencil to the holder by sliding it in. Press the other needle into the point that you want to make the center of your circle. Rotate the pencil around in a circle while holding the needle still to make a perfect circle.  If you don’t have a compass and don’t mind a possible imperfection, you can use any perfectly round object, like a lid, cover, or bottle, as a straight edge and trace around it. You can use a pen if you want, but you’ll have to start from scratch if you make a mistake. Keep the compass needle in place and rotate your pencil to the top of the circle. Pull the pencil straight down towards the needle after loosening the hinge to create a radius. Depending on the style of your compass, you may need to put a dot in the center after moving the needle then draw the connecting line yourself with a straight edge. The straight line can be vertical (12 or 6 o'clock on the clock face) or horizontal (9 or 3 o'clock on the clock face). The segments you create then follow either a clockwise or counter-clockwise sequence. Place the small hole in the bottom of your protractor directly on the point where your compass needle was. Line the straight line up with the 90-degree hash mark on your protractor. The hole at the bottom of your protractor is called the crosshair and it is used to make perfect 90-degree angles by creating a straight line with the 90-degree hash mark. Keep the crosshair centered on the center of your circle and add your first data point to 90. Find this number on the outside of your protractor and make a hash mark. Then, draw a straight line from the hash mark to the center of your circle. Make each new line that you make the 90-degree center for the next section that you calculate.  For example, if you were making the farm animal pie chart, your first number is 144. Add 144 to 90 to get 234. Make a hash mark at 234 degrees and then make your line. Rotate the protractor and use the line you just made as the new...
