First, the sound inside the train is put in our daily life. Everyone may have taken the bus or subway. When you are riding, if someone in the car makes a very disturbing sound with a mobile phone, you will feel very uneasy. But everyone is embarrassed to mention, to avoid conflict, these traffic rules have stopped this kind of behavior very well.
Second, begging and lying down on the train With the gradual improvement of people's living standards, people will feel pity when they see a very poor beggar on the road. However, in this society, many beggars are disguised. They cheat and beg for a lot of property every day in this disguised way. Shanghai traffic regulations prohibit begging and lying in the train, which avoids such things and prevents people from lying down and occupying public resources.
3. Smoking on the train As we all know, smoking is harmful to health, because nicotine in tobacco is harmful to human body. Smoking on the train is a very uncivilized phenomenon and irresponsible to the life and health of others. I think smoking on the train should be banned the most.
