If you go to HK for sightseeing, you should apply for visit entry permit. First, prepare the required documents including your passport and copy of its data page, the filled-out application form attached with a passport-sized color photo taken recently, proof of your financial standing, flight itinerary and your travel plan to HK. Afterwards, submit your application to the embassy of PRC in Nigeria to apply for it. It costs 6700 naira.
