What's wrong with people always pouring dirty water at my door?

I think this question is very impolite. It is very bad to throw dirty water at someone else's door. It's uneducated and uneducated. A man who doesn't pay attention to civilization won't put water on someone else's doorstep. First of all, it's unsanitary. On the contrary, if he can serve others better, he should do more good deeds and not do illegal and unpopular things. This kind of person will throw water at other people's doors and let them point at their backs. It is immoral to pour dirty water into dirty wells, which is not good for people's moral quality. It is immoral to pour water at someone else's door, and it is a phenomenon to step on shoes in summer. In winter, you pour dirty water into someone else's door, the water freezes into ice, and the walkway is broken because of falling down. This is very inappropriate. So be polite and know how to be a man.
