To visit China, you need a valid passport with at least 6 months validity and 2 blank pages, as well as a visa obtained by filling out the visa application form. Depending on the purpose of visit, additional documentation is required - for business, proof from your Chamber of Commerce is needed, and for study, a letter of acceptance from the university. While in China, visitors can see landmarks like the Great Wall and Forbidden City, experience local customs like tea drinking, and visit nature reserves to see giant pandas or scenic areas like Jiuzhaigou Valley.
