Original Vintage 1970s Chinese Propaganda Poster Chairman Mao This poster has been cropped to fit into a frame and there is wear at edges.

Although the construction of the canal was influenced by the events of the Cultural Revolution - the pernicious influence of Liu Shaoqi and "his clique" are mentioned time and again - there are no indications that Mao ever visited the project, as the poster above suggests. It is unclear whether this Canal of Happiness is the same as the Red Flag Canal.
