I am a Korean, and I am going to Shenzhen with a Chinese multiple-entry business visa. Can I go to Hong Kong for two days in Shenzhen? What are the requirements when I return to Shenzhen?

1. Hong Kong provides visa-free entry for Korean passports. For Korean passports traveling from Shenzhen to Hong Kong and back to Shenzhen, as long as the Chinese visa is valid, there are no other requirements. 2. If you are leaving Hong Kong to get an entry-exit stamp, you must exit China Customs-Enter Hong Kong Customs-Exit Hong Kong Customs-Enter China Customs. When you come back, you must have these four entry and exit stamps to complete the customs clearance record. 3. Suppose you are traveling from Luohu Customs to Hong Kong and enter Hong Kong Customs. After entering Hong Kong, you can follow the flow of people. You cannot go back. You must buy a 20 yuan train ticket and take the train one stop to Sheung Shui Station. You don’t have to leave the station. You walk across the street and take the train one stop back from Sheung Shui Station. Just go to Luohu Station. Go back to Luohu Station and use the 20 yuan ticket to exit the station. After leaving the station, go directly out of Hong Kong Customs and then enter Luohu Pass. In this way, an exit record can be completed. If you leave the country every 30 days, you can make a round trip again after 30 days. Each trip only costs 20 Hong Kong dollars. It takes about 1 hour.
