This is a report on the Internet today, saying that Chinese tourists are not welcomed by the locals when they travel to Lake Baikal in Russia's East Asia region! In fact, it is not an ecological problem, but an ideological and psychological identity problem. Because they don』t like too many Chinese people to go there to disturb the local peace and tranquility of many years. As I said last time, tourism is part of culture, and cultures are different. People of different cultures may have conflicts when they are together. The above is an example of cultural conflicts. The country has boundaries, and boundaries surround a large group of people in a limited area. The rule of the country depends on the people supporting the government to carry out. To make people cohesive, can be through various means, such as patriotism, nationalism, the same religion, similar culture. These are all at different levels and scopes that unite people to form a powerful force. The construction of the country, the development of the society, and the people need these forces to live a better life! This is why China wants to block the Internet, because a society with a large population provides a huge internal market invisibly, and it has enough ability to maintain and develop its own culture. The aspiration of the people is the huge political force that maintains the stability of the government. It is the guarantee of rejection and resistance to external influences. This is the resource that all countries have been fighting for before. The Russians are desperately expanding their land and are wary of outsiders. The country advocates patriotism, it has a positive effect on each country itself. But all of these are double-edged swords. When you try to protect the interests of a certain country, you are bound to hurt the interests of groups outside the country, because many resources in the world are zero-sum. For example, territories, national sovereignty, etc. Now with the development of civilization, human energy is getting more and more, and national borders can no longer restrict the flow of people. The world needs to be one, to open up let people flow, and to rationally arrange resources on a global scale. This is a new challenge to mankind in the 21st century.
