What should I pay attention to when sharing a room with a stranger for the first time?

Be sure to take care of your property and take care of your valuables. When you first shared a rent with a stranger, you didn't know much, and you didn't know what kind of person you shared it with. What if his hands and feet are not clean, you don't know, you don't guard against her, and finally you steal your own things, and there is no evidence to prove that it is stolen, and finally the relationship is very stiff. So in order to avoid this situation, you should take care of your own things.
