Travel to China is a lifetime experience and a better way to understand China. Only when you are there, you may start to appreciate and understand what a difference to live in a nation with a population of 1.3 billion.

China offers variety choices for visitors. If you are interested in Chinese history, Chinese culture and Chinese scenery, your trip will be very fulfilled and very interesting. If you want to enjoy a peaceful sunshine beach holiday, there are plenty of tourist areas along the coastal line, which have unspoiled beaches and luxury hotels for visitors. In Hainan Island, the beautiful Sanya beaches are opened the whole year around and there is no winter in this island. If you want excitements and nightlife, stay in big cities. There are many places every night for international gathering. If you are adventurers, go to remote areas to watch wild life or visit minorities(少数民族) to see how they live in the hillsides or desert. If you are sporty, take a cycle trip along the countryside, enjoy the rural(田园的) life and meet with Chinese people long the route.

You may have heard or read a lot about China from books, newspapers, magazines and TV programs. Some of them are true but most of them are out of date, incorrect or even false. China is different from many of your previous experiences and may shock you in many ways. This is what China is!

This country is changing and progressing every day. Yet it is still a developing country. After the economic reform, most of the developments concentrate in major cities and remote areas(边远地区) are still very backward. China is a very populated nation and people have to cope with the crowded environment. Foreign visitors may not get used to the mentality of the people and sometimes become frustrated with the situation, which they never experienced before. Basically Chinese are reserve, peaceful and nice. They are very polite too but in their own way. When a foreigner is willing to take a more positive attitude to recognize the difference, the trip will become worthwhile or you may ruin your trip completely by unreasonable expectation and misjudgment of the people in general.
