Tibet(西藏) is among the most popular places for Chinese tourists. The number of travellers of Tibet has grown by 10% every year for a few years. Since July 1, 2006， when the first train ran 1,956 kilometres from Xining to Lhasa, more and more people have been to Tibet.

    The train stops at several famous places along the way, such as Qinghai Lake, Kunlun Mountain, and the Potala Palace. Passengers can also enjoy many activities during the journey, like Tibetan dancing and karaoke.

    On the train, passengers can have tea, eggs and noodles for breakfast, and fried chicken and green vegetables for lunch and dinner. Unlike most other Chinese trains which have openhole toilets, this one has special toilets which can collect the waste. There is also a special rubbish system(系统) in the train that keeps the environment clean. All the windows on the train can protect people from the bright sunlight. TV and electrical sockets(插座) for computers and mobile phones can be  found on the train.

    Because there isn't much oxygen there, trains will have oxygen masks(氧气罩) for those who need them. It makes passengers feel more comfortable when they have enough oxygen on the famous “roof of the world”. There are also doctors on the train to make sure that all of the travellers are safe.

Beijing is the capital of China. There are many places of interest. The weather in Beijing is very hot in summer, and very cold in winter. The air pollution is serious in that city. But there are still millions of visitors from all over the world every year.
