Of course, because Hong Kong has clearly become a territory of the Central Plains since the Qin Dynasty. Until the Qing Dynasty's defeat in the mid-19th century, the territory was ceded and leased to the British in batches to become a colony, and Hong Kong opened for port development. In the 1980s, China and the United Kingdom addressed the issue of Hong Kong's future and signed the Sino-British Joint Declaration in 1984, deciding that the People's Republic of China would resume the exercise of sovereignty over Hong Kong on July 1, 1997. China is committed to implementing one country, two systems in Hong Kong. Hong Kong will maintain its capitalist system and original way of life, and enjoy a high degree of autonomy in all matters except foreign affairs and national defense. That is, "Hong Kong people govern Hong Kong with a high degree of autonomy."
That is, before 1997, Hong Kong was a British concession. Not only did it fly the British flag, but even the currency was engraved with the Queen's face and was in English. Even today when I go to Hong Kong, many people’s Mandarin is very substandard. But Hong Kong people are hospitable and the social order is also very good.
In terms of culture, Hong Kong has absorbed the essence of Eastern and Western cultures. For example, in terms of food, there are both traditional oriental snacks and authentic exotic delicacies. Hong Kong is a city that combines both Chinese and Western elements, including "Wong Tai Sin Temple" and "Lan Kwai Fong". Hong Kong people are still traditional at heart. For example, many families have family reunions on the first and fifteenth day of every month. They attach great importance to Feng Shui.
