Many people are like this, ignoring public morality and doing things that harm others and benefit themselves. However, even if disturbed, many people will not stop such things. China people pay attention to harmony, and it is better to do more than one thing, so they indulge this kind of people.
I don't usually talk to such people. If you can't stand it, then stay away from him. He can be as tall as he wants. I'm sorry if it's not far. Please put on headphones to listen to music.
In short, such people need to be stopped, otherwise this phenomenon will increase.
