我们该怎么做才能提高我们的跨文化交流

How to talk about each other between different places ? There are different ways.
if you have friends have been there ,you can talk to them;Most Americans do not like to use Mrs.or Miss.they find there words too formal.They like to call you by your firs name.For example,a man may say,"glad to meet you.l am paul Miller.But call me paul".A lady you first meet may say,"please do not call me Mrs.Smith,just call me Mary"and so on.
And we can also read some books.Sometimes,they are better than a friend ,because you can always read them whenever you want.
Also we should talk with them who come different places,so we can know each ether better.I think we are all friends.
