advice what is the procdeture and how much visa charge and how many days take visa procediture

Indian passport holders don't need a visa to Hk for less than 14 days, so I think you just have to apply for a China tourist visa for your trip to Shanghai.

You may just go to the China Embassy in UAE to apply for the visa with the documents listed below:
1. Original passport with blank visa pages and validity of more than 6 months
2. UAE resident visa valid for more than 6 months. (Excluding GCC applicants)
3. Application Form which must be completed neatly and signed by the applicant
4. One passport photo
5. Copies of the data pages of the applicant's passport and UAE resident visa
6. A No-objection letter from your company stating your position ,monthly or yearly salary
It normally takes 4 working days to process the visa application. It costs 110 AED
