Why are China's Qing Dynasty photos glazed over?

First, photography is still poor. Second, people's thinking is rigid and their facial expressions are not rich. Third, the economy is underdeveloped, people's comprehensive quality is poor, and there is no shining light of wisdom in their eyes. In addition, you can look at the photos of Liang Qichao, Kang Youwei and even Li Hongzhang at that time, which are much better than the eyes of ordinary people and officials.
