Mr. White is our English teacher. He has  come in China for more than two year.  He has been to many interesting places in Beijing,  and he has not yet been to many  others parts of China. Last week he goes to Mount Emei in Sichuan Province with his family. Many people like travelling by  the air, but the White   family think that travelling by train is the best, it is much  cheap and far more enjoyable than a trip by air. They had a wonderfully train trip to Chengdu  after they went on to Mount Emei by bus.
