There is also a simple computer drawing method. Select the curve shape and draw a semi-circular arc on the canvas. The method of drawing on paper with a pen is the same. Select a straight line in the shape box, and hold down the shift key to draw a horizontal straight line above the arc. Continue to use a straight line and draw a base under the arc as the bottom of the bowl. Select a straight line again, hold down the shift key at the bottom of the bowl and draw a horizontal straight line. Set the curve to the thinnest, and draw three lines above the bowl as shown in the figure below as the hot air emitted by the rice.
