Chinese Communists turned the flooded area into a recruiting ground, directing survivors' anger towards a common enemy to bring them into their ranks. By the 1940s the area had evolved into a major guerrilla base known as the Yuwansu Base Area. Repairs Attempts to seal the breach and return the river to its former course were made in 1946 by the KMT with assistance from UNRRA. Work began in March and was completed in June, but the dams were again destroyed by large summer flows. Subsequent repairs succeeded and were eventually completed in March 1947.
