Many Chinese students like to study in English colleges. There is something important that they need to know well.
English people can't accept those people who likes speaking loudly in public. They always speak in a low voice and they are used to speaking quietly. Because they all think it's impolite to make much noise or call somebody loudly.
They often say "please" before asking for something, and say "thanks" after receiving help or service. It's said that the expression used most in public is "Excuse me". Someone, for example, will say it when they want to order some dishes in a restaurant or do shopping in a store. Importantly, some people will greet each other with it when they meet for the first time. What' more, when a small accident happens to some persons, they will be ready to say it. Of course, "cheers" is also used widely. It's another way of say "You're welcome" or "Goodbye".
Women and old people are respected by most people. English often let women and old people first. They can get on the bus first and do anything first in many situations. And they all like to do things waiting in a line. You can't believe that there are only a few people waiting to get money in front of the ATM machine in a line. You can't see the people jump the queue. It'd really a traditional morality (传统道德). We should learn from them.
