After shopping in Harbour City, walk to the Bell Tower and Avenue of Stars, and then take the Star Ferry (which is located at the entrance of the Bell Tower and Harbour City) to Central. In Central (where there are many shopping malls), you can also visit the Legislative Council, Bank of China Building, HSBC Building, Court of Final Appeal and St. John's Church, then take the subway to Causeway Bay (where there are many shopping malls, sogou is there) and go shopping in Causeway Bay. Then take the subway from Causeway Bay to Wan Chai, then walk to Golden Bauhinia Square for sightseeing, buy tickets at the pier near Golden Bauhinia Square for a night tour of Victoria Harbour, and then take a bus from Wan Chai to Hong Kong and Macao Pier. Have a nice trip.
