Why is the picture of Dongfanghong tractor printed on food stamps?

Dongfanghong tractor pattern is one of the common patterns on food stamps, cloth stamps and other commodity vouchers circulating in Chinese mainland during the planned economy period. This is because in 1950s and 1970s, China implemented a planned economy, and both rural and urban development needed the support of tractors. Dongfanghong tractor was the representative brand of domestic tractors at that time, so it was chosen as the pattern. In addition, Dongfanghong tractor symbolizes the rise of agricultural modernization and industrialization in China, so it is widely used in various vouchers and becomes a symbol of the times.
