When a primary school student wipes a typo, the one that I want to wipe is fast and clean. It is often rubbed with a rubber squeegee and then rubbed. On the contrary, the typos are erased, and the book is rotten. Especially the students who draw, the sketching of the backlight part, often painted, greasy, dirty, and at this time, if you continue to rub repeatedly, even spit, it will be broken.

The correct method should be: first dry on a piece of empty paper, rub a lot of "rubber surface", then gently pour the face on the part to be wiped off, then gently rub it on the face with an eraser. In a short while, it will be clean and it will not damage the paper at all.
