The people of China have very tough qualities. When they encounter numerous difficulties, they can solve problems with perseverance and great unity.
Another reason is that in ancient times, it was an era of absolute monarchy. At that time, there was a very unified idea that people served the monarch wholeheartedly.
It is precisely because of this that we unified our thinking. The monarch of China also wants to continue his dynasty, so China has such a long history.
Although China has experienced countless wars, it still stands at the top of the world, precisely because the people of China have indomitable character in the face of difficulties. Never give up when you can't reach the goal you want.
Moreover, the people of China have a kind of perseverance in their bones, and they will never give up even in the face of any setbacks.
