9. I finally visited the Hong Kong Museum of History on Friday, so I wanted to share something that I found particularly interesting. When the Chinese relinquished control of HK to the British following the end of the first Opium War, the population of HK was only about 25,000. At that time, it was a backwater of little importance to the Chinese empire. By the beginning of the World War II, the population had increased to one million. However, the Japanese forcibly repatriated about half of this population back to mainland China. Since 1947, the population of Hong Kong has grown from about half a million people to seven and half million. I was amazed by this level of growth especially given that urban sprawl cannot exist here!
