Travelers to China require a valid passport and visa, with passports needing to be valid for at least 6 months after entry. The document outlines key information about China, including its geography, population, official language, currency, and tourist attractions, as well as a detailed 7-day travel itinerary for cities like Shanghai, Nanjing, Yangzhou, and Hangzhou. It also provides travel tips and estimates for expenses involved in the trip.
