During 150 years of britannic dominion, what at the beginning was considered “a useless piece of rock” became instead one of the main places in the world for exchange of good, besides being among the most important business sites between East and West. Hong Kong (the parfume Port in its mother Language) assimilated the both cultures which for more than a Century made this small Island a mega-city of the third millennium. When in 1997 Hong Kong came back to be part of the People’s Republic of China under the formula “One country, two systems”, thousands of Chinese people moved from their homeland to the small and already overcrowded island, looking for a job. Thousands of them slept in the streets, while the number of crimes increased, causing a new and unexpected emergency in the newborn SAR (Spercial Administrative Region).
