There are great differences between Hong Kong and the Mainland in political system and historical environment, which also affects the way of thinking of Hong Kong people. Hong Kong is a citizen culture, accustomed to the city-centered way of thinking, while the mainland is a national culture, accustomed to national pride. For example, Shanghainese used to discriminate against foreigners, but at the same time they had a strong sense of national pride. On this basis, there will be great differences in culture and value orientation, and the recent occupation of China has also transformed this thinking inertia into ethnic contradictions. Take the United States as an example The cultural environment on the east coast of the United States is very different from that on the west coast. If you fly from new york to Los Angeles, those who stand in the aisle of the plane and pack their bags and let others wait to get out of the way are new york people, not Californians. Both American cultures have different humanistic environments and personalities, and the reason is the cultural differences arising from the vastness of the region. In fact, mainlanders should also understand the ecological structure of Hong Kong people. In recent years, tourists have really pushed up the rent of incense shops, and high-end shops have squeezed ordinary means of subsistence. The subway MRT is crowded with traffic, and high-end consumption has not brought much benefit to the lower class in Hong Kong, and all the money has been earned by the rich. Living in the mainland basically does not involve Hong Kong people, but people living in Hong Kong meet a large number of mainlanders every day. The increase of mainlanders is changing the existing cultural and ecological environment in Hong Kong, and the political system and history education are different, so the anger of Hong Kong fans still needs to be treated correctly.
