China, 1960+/-

Wikipedia says:

The Great Chinese Famine was a famine that occurred between 1959 and 1961 in the People's Republic of China. Some scholars have also included the years 1958 or 1962.

This photo has to do with the famine, and unless they were digging irrigation or creating terraces, it doesn't look much like farming, but it is from a YouTube video sharing evidence that China's population might be much lower than they claim.

Video should start about two images before this one (narratively in context).
As to the wheelbarrows, though, they have a large wheel and the tray is flat above that. Not as stable as a European wheelbarrow with the wheel smaller, and out front.
