What are the similarities between the fame experiences of documentary photographers? Please give an example.

Most of the documentary photographers who became famous in the late Qing Dynasty and the Republic of China mainly shot war themes, or were related to shooting valuable political content. Hong Rong (1828— 19 12) was an outstanding representative of the reformists in the late Qing Dynasty. 1847 studied in the United States, 1854 graduated from Yale university, becoming the first person in China to graduate from an American institution of higher learning. In the 12th year of Tongzhi (1873), Peruvian envoys came to China and signed a treaty with China to recruit Chinese workers. Before that, a large number of Chinese workers in Peru had been treated inhumanely. The China government had heard about it for a long time, but there was no evidence to reject Peru. So Li Hongzhang, who was in charge of this matter, sent Hong Rong to Peru to investigate the situation of Chinese workers to decide whether to sign a contract. Hong Rong described this process in his memoirs: "Those Chinese laborers whose backs were smashed, scarred and unbearable were photographed and presented to the world. I secretly took this photo at night, and no one knew about it except a few Chinese workers who were abused by it. The names of these Chinese workers were also obtained through secret notification and private agreement. Peruvian Chinese workers' workshop, a livestock farm. All kinds of barbarism in the wild are cruel and unreasonable, and photography is unique. With this conclusive evidence, there is no room for defense.
