I M IN JORDAN HAVE CHINA VISA I WANT TO VISIT HONG KONG WHAT I HAVE TO DO

What's your nationality? Citizens from some countries can visit Hong Kong for a certain period without a visa. Jordan passport holder can stay in Hong Kong for up to 30 days without a visa. FYI: https://www.travelchinaguide.com/embassy/pdf/hongkong-visa-free.pdf
If you are not the citizen of the countries, you can either apply for a Hong Kong visa from China embassy in Jordan or from Hong Kong Immigration Department by post.
