The photos did not reveal the most important things: why the average life expectancy was around 25 years and why China was deemed so helpless that it could not regain its lands from foreign occupation forces, nor stop the brutal Japanese invasion. China's population figures, already much revised by Western and local comprador propagandists, show Chinese population increased by a little over a hundred million from 1911-1949. However, from 1950 to 1960, in only 10 years, China's population increased by about 130 million. Even if we give the excuse that China lost about 30 million people because of the Japanese invasion, that would still mean that after Liberation, the first 10 years alone saw population increases matching the previous 30 plus years of Republican China.
The low population increase under Republican China was no accident: it was due not only to wars, but also to massive inequality and unending starvation of the lower classes, as well as starvation-related diseases and other illnesses. This is something that cannot be revealed by photos from the bourgeoisie.
And I've not even mentioned how China's population increased by about 300 million from 1965 to 1975, again in only ten years.
