Many people are like this, ignoring public morals and doing things that are detrimental to others, but even if they are disturbed, many people will not try to stop such things, the Chinese people emphasize the importance of harmony, and it is better to do more than less, so they also condone such people.
I usually don't take care of such people, if it's really hard to bear, just stay away from him, how he likes to get high on his own, if he's not far away, I'm sorry, please put on your headphones and listen to the music.
All in all, these people need to be stopped, or else this phenomenon will become more and more common.
