What certificate do I need to apply for to go to Shenzhen?

No specific documents are required to go to Shenzhen.

Shenzhen is a sub-provincial city in Guangdong Province, China. As a special economic zone, traveling, business or residence in Shenzhen generally does not require special documents. Chinese citizens can freely enter and exit Shenzhen with their ID cards, while foreigners need to hold a valid passport and visa. Citizens of some countries can apply for a visa on arrival or apply for an electronic visa when entering the country. In addition, if you go to Shenzhen to attend conferences, exhibitions or other business activities, you may need to apply for a corresponding business visa or invitation letter. But generally speaking, traveling to Shenzhen for tourism and business activities is relatively convenient and does not require special document procedures.
