In what events in the history of China in the 19th century did you encounter manifestations of nationalist ideology, and how would you evaluate them?

The first feature of Chinese nationalism is its statehood. Not ideology, not language, but statehood is the backbone of Chinese nationalism. Its second fundamental feature is great power. The third fundamental feature of Chinese nationalism is its reliance on culture.
The widespread “Westernization” that accompanies globalization has also affected China. The appearance of hundreds of millions of Chinese has radically changed, especially in megacities: not only clothes and hairstyles, but also behavior. Western popular culture crowds out national culture. This threatens society with denial of its own heritage, the growth of nihilism, especially among young people. The state is trying to create a “new national culture” by offering traditional values ​​instead of Western ones. These are often harsh and unpopular measures (for example, restrictions on the Internet), but this is how China protects its own cultural and social values, which, according to the authorities, increases the stability of the state.
