Do we need visa to travel from Shenzhen to Hong Kong?

Q: Hello. I'm going to Mauritius. I will go by bus from Wenzhou to Hong Kong... Wenzhou to Shenzhen, then Shenzhen to Hong Kong. Do we need visa to cross border from Shenzhen to Hong Kong. Thanks.

Citizens of many countries can visit Hong Kong visa free for a period of various lengths. If you hold passports of Mauritius, you can visit and stay in Hong Kong for up to 90 days with no visa. Check with the Hong Kong Immigration Department to make sure.
