What do you mean? can you elaborate more on this statement if you don't mind?
150 years ago, China was at the end of the Qing Dynasty. At that time, the vast majority of Chinese elites still firmly believed that they were the so-called "Heavenly Kingdom", and showed absolute arrogance and ignorance in the face of Western science and technology. According to the classical Chinese theory at that time, the science and technology of the West were nothing more than tricks stolen from China, and the West was all barbarians who did not understand the ways of Confucius and Mencius.
Looking back, the three most obvious characteristics of the Chinese people 150 years ago: disunity, ignorance, and insensitivity, and it was these three characteristics that made China fall into a century of humiliation.
Of course, modern Americans are still far from the Chinese 150 years ago, but certain similar trends are enough to attract the attention and self-examination of American elites.
