What kind of adhesive paper can be used to paste the happy characters on the wallpaper so that it can be easily removed without damaging the wallpaper?

Step 1: Prepare the word "Fu" to be pasted (here, the word "Fu" is used instead).

Step 2: Turn the red paper to the back and squeeze a proper amount of toothpaste at the four corners of the back.

Step 3: Apply the toothpaste evenly with your fingers, and increase or decrease the amount of toothpaste according to the paper size.

Step 4: Stick the scarlet letter on the wall, and the toothpaste plays an adhesive role. When it is torn off, the toothpaste body is white and dry, so it won't hurt the wall and red paper.

Precautions:

1. Dust on the pasted wall should be removed, otherwise the pasted happy characters will easily fall off.

2. Don't choose colored toothpaste, it will leave traces on the wall.

Red paper will fade when it is wet, so don't stay on the wall for too long.
