What if I hear someone knocking at the door in the middle of the night?

It's really penetrating If I'm scared to death,

If the door is not very strong, it can be pried open even if it is locked.

What's that door? Is there no cat's eye on the door? If you can't, just press one, but the other person can't help it when he covers his face. After reading it, he won't recognize it.

If not, install the safety door. If it doesn't fit, block the door with a heavy object before going to bed. (It doesn't seem realistic either. )

Or prepare something for self-defense when sleeping, such as sticks and knives (what am I talking about)

It seems that if that person comes again, it will be too late to call the police temporarily. Besides, if he doesn't come in, people will say you're lying.

Why not find a few people and wait for him to catch him, but it's time-consuming, laborious and expensive.
