To the OP, you will go through Hong Kong (not China) immigration and customs upon arrival in Hong Kong. Connecting through Taipei, you will follow the signs for the transfer area, show your onward boarding pass, go through a quick transfer security check and be back upstairs to take your connecting flight.
You will never encounter China immigration or customs on this itinerary.
