1956 The slogan "There is water in big rivers, but there is no water in small rivers" came into being after the nationwide "co-operation", which soon became a classic metaphor for rural socialist education.

This is a metaphor for the connection between the collective and the individual. The collective is like a big river, and the individual is like a small river. With the strength of the collective, everyone in the collective is relatively rich. If the strength of the collective declines and collapses, and the individuals in this collective have no income.

This is a truth of life.
