With a population that is mainly ethnic Chinese and a special historical background, Hong Kong is a global city in which Chinese traditions intertwine harmoniously with Western culture. You will find multiple denominations of churches sharing space with Chinese joss houses, temples, mosques, and synagogues. It is not surprising to see elderly residents playing ancient Chinese board games on digital tablets. In Hong Kong, people celebrate the Christmas and Easter holidays with the same fervour as they enjoy Buddha’s Birthday and Chinese New Year. Hong Kong is also an inclusive and innovative city where state-of-the-art skyscrapers are designed in consultation with Feng Shui masters.
