Waqas, you should apply for a tourist visa to go there. You should first prepare the required materials containing copy of your passport, the application form attached with a passport-style photo, transportation arrangement, proof of your financial support and your travel itinerary to HK. And then submit your application to Foreign Affairs & Business Service Office, CCSC or Al sandross international Est to apply for it.
