Do you need to apply for a visa in Sanya?

Legal analysis: No, because Sanya is Chinese territory, Chinese citizens do not need a visa to travel to Sanya.

Legal basis: "Exit and Entry Administration Law of the People's Republic of China"

Article 6: The state establishes entry-exit border inspection agencies at ports open to the outside world. Chinese citizens, foreigners and means of transportation shall exit and enter the country through ports open to the outside world. Under special circumstances, they may exit and enter the country from places approved by the State Council or departments authorized by the State Council. Entry and exit personnel and means of transportation shall undergo exit and entry border inspection. Entry-exit border inspection agencies are responsible for the management of restricted port areas. In accordance with the needs of maintaining national security and entry-exit management order, the entry-exit border inspection authorities may conduct border inspections on items carried by entry-exit personnel. When necessary, the entry-exit border inspection authorities may conduct border inspections on goods carried by exit-entry transportation vehicles, but they must notify the customs.

Article 9 Chinese citizens who intend to leave or enter the country must apply for a passport or other travel documents in accordance with the law. Chinese citizens traveling to other countries or regions also need to obtain a visa or other entry permit from the country of destination. However, this does not apply unless the Chinese government has signed a mutual visa exemption agreement with the governments of other countries or if the Ministry of Public Security or the Ministry of Foreign Affairs provides otherwise. Chinese citizens who enter or exit the country as seafarers or work on foreign ships must apply for a seafarer's certificate in accordance with the law.
