Try to clear customs as early as possible in the morning (Luohu or Futian port), for example, before 8 o'clock. Buy Hong Kong Octopus Card after customs clearance, which is convenient for taking subway, bus, fast food, convenience store and snacks.

First stop: Ocean Park-take the train/subway to Ocean Park after customs clearance (get off at Ocean Park Station). It will arrive in an hour and a half. I played for three hours and left around noon.

Second stop: Hong Kong University-It takes only about 20 minutes to leave Ocean Park and take the subway to Hong Kong University. Then leave the station at "Hong Kong University Station", first look at the map of the station and have a light meal near the station. Then follow the directions on the map of the station to the University of Hong Kong. It only takes 10 minutes to walk. Can stay 1 hour. Leave the university around 3 pm.

Third stop: Central-leave the university and return to the subway station. Take the subway back to Central Station. Just 10 minutes. Look at the map of the station first, find the location of the ferry, and then walk along the seaside to reach the ferry. It is estimated that it will leave Central at 5 o'clock.

Fourth stop: Yau Tsim Mong-take the ferry to "Tsim Sha Tsui". Take the ferry with Octopus card and browse the beautiful scenery of Victoria Harbour! When you arrive in Tsim Sha Tsui, you can visit the shipping center, shop nearby, buy brand-name bags and go shopping (Octopus cards can eat fast food: KFX, Madang X, Everybody X, Big Fast X; You can also shop in a drug chain store: X, X). If you have energy, you can go directly to Jordan, Yau Ma Tei and Mong Kok. Otherwise, take the subway or take the bus along Nathan Road. You can save some energy.

You can go shopping until 10 at the latest, but you have to go back to China through Luohu customs. If you want to pass Futian Port, you must return before 9 o'clock. All the buses and subways mentioned above can be taken with Octopus cards. There is no need to prepare small change.

I will help you this afternoon.
