1. Clean the tiles first. If the weather is cold, warm the wall with some hot water in the thermos, stick a hook on it and knock it with a small hammer. You can't hang things until 24 hours later.

2, you can use a cotton swab to evenly smear the egg white liquid on the sucker, and then stick it on the tile or glass, and then hang the heavy object after it is completely dry.

3. Put some soapy water on the back of the sucker, and then stick it on the wall to make it stronger.

4. Reinforce the sucker. You can also apply a little skin care oil on the back of the suction cup and stick it on the wall for a day before using it.

5. Put the plastic sucker into hot water and take it out 10 second, which can also strengthen the hook.

6. There is an easier way. Drop some water into the sucker and quickly stick the sucker to the plane.
