When using the toilet paper with reel,we will ignore the division of the dotted
line , and often tear a half of the paper,which leads to pollute the others. By
marking the red dot in the sides of the dotted line , we can remind the user to
tear the paper along the red dot,and let them realize that they should save the
use of the paper.
