The Four Series of Big Rivers was a long novel written by the financial writer Anai. It comprehensively, meticulously, and deeply showed the economic reforms, changes in social life, and changes in people's mental outlook since China's reform and opening up.

The entire quartet truly restored the pioneering life, struggle, and fate of the leading figures in the reform and opening up period.
