Torrential rainfall over the middle Yangtze basin in July 1935 overwhelmed embankments in Hubei and Hunan, flooding farmland and towns that had barely rebuilt from 1931. Millions were displaced.

The repeat disaster hardened the argument for large-scale river control on the Yangtze, an engineering debate that continued for the rest of the century.
