What documents should foreigners go through when traveling in China?

Foreigners who want to travel to China need to apply for a tourist (L) visa from China's embassies and consulates abroad. Those who travel to China in groups of more than nine people can apply for a group tourist (L) visa. Foreigners who go to Shenzhen, Zhuhai and Xiamen Special Economic Zones may apply for "Special Zone Tourist Visa" directly to the above-mentioned port visa authorities. If you stay in Hainan Province for business, tourism and visiting relatives for no more than fifteen days, you can temporarily apply for an entry visa at Haikou or Sanya Port. Foreigners in Hong Kong do not need to apply for an entry visa to travel to Shenzhen Special Economic Zone for 72 hours. When applying for a visa, foreigners must answer the relevant questions and perform the following procedures: 1. Provide a valid passport or a certificate that can replace the passport; 2. Fill in the visa application form and submit a recent 2-inch half-length bareheaded photo; 3. Submit the certificates related to the application for entry and transit. Foreigners holding tourist (L) visas must pass through ports open to foreigners in China or designated ports, accept inspection by the frontier inspection authorities, submit valid passports and China visas to the frontier inspection authorities, fill in entry cards, and enter the country after being checked and approved by the frontier inspection authorities and stamped with the entry inspection stamp.
