At the border with mainland China, Hong Kong was a fantastic nose thumb by the capitalists to the communists. The former English territory has lost none of its appeal, even though Guangzhou aspires to better it economically and culturally. This won't be easy. Hong Kong is fascinating and intoxicating.
Nowhere else in the world do you have such a concentration of skyscrapers in such a small area. On extremely windy days you can see some sway. They are, however, designed to withstand storms and earthquakes. Take the Avenue of Stars honouring the cult classics of Hong Kong cinema. Shops and markets are open day and night. If it's bought or sold, you'll find it here. The most typical markets are Yau Ma Tei and Mong Kok. Try the fried noodles and steamed goodies at a street stall. If you have time, take the ferry to the islands, peaceful havens where time stands still.
