A huge flood control sluice gate near Runhe (潤河), see also BG E37/76 and BG E37/77. The project was already dismantled in 1958.
In the lower right of the image is a Russian expert, wearing a brown suit and a hat. Possibly the same person is depicted on the 1951 poster "The Soviet water conservancy expert Comrade Bukefu helps us to bring the Huai River under control".
The title is a Mao quotation.
