As long as you believe that the country can develop well in the future, it is a kind of national confidence.
Self-confidence can be established by comparison, comparison with yourself and comparison with others.
From the comparison with yourself:
The key to the establishment of people's self-confidence comes from the long-term feeling of the changes in the surrounding environment. Judging from the feelings of these decades, our living standards have indeed improved, and the overall public security of society and the state of the country are in a relatively stable state. So we should think that our country is on a good road. We were right.
Compared with other countries,
Compared with foreign countries, I think it is more wise to compare the time it takes to complete the same thing at home and abroad. It is an unconscious behavior to laugh at the system established by China for decades with the institutional advantages established by the United States for hundreds of years. It takes less time for China to reach the same level as the United States in the fields of science, education and humanities. Although there is a height gap between them, we should have full confidence in the development speed of China.
In a word, our country can make us confident.
Self-confidence should be viewed from a long time span, because it is irrational to judge the state of national development because of a social phenomenon and claim that it has lost national information.
