1. Prepare tools: Make sure you have a scraper or a hard plastic scraper, which will help you tear off the wallpaper more easily.

2. Turn off the water: Before tearing off the wallpaper, please turn off the water near the table to prevent the wallpaper from being soaked in water and becoming more difficult to tear off.

3. Heating the wallpaper: Use a hair dryer (set at low temperature) to heat the wallpaper. This will make the glue easier to flow and tear off. Please be careful not to let the hair dryer get too close to the wallpaper to avoid damaging it.

4. Gently tear off the wallpaper: from the corner, gently tear off the wallpaper with a scraper or scraper. Please be sure not to use too much force to avoid damaging the wall. If you encounter difficulties, please continue heating and tear it off as much as possible until you succeed.

5. Clean up the residue: After the wallpaper is torn off, some glue residue may be left. Wipe the residue gently with a damp cloth or eraser to ensure that the wall is clean and tidy.

6. Check: Check whether the torn wallpaper is damaged or wrinkled. If necessary, you can cut off the extra parts with a blade and stick them back on the wall as needed.
