Zhou reported that by the end of 1979, 51% of production teams had adopted the production unit responsibility system, and 10% had adopted the household responsibility system; there was a significant production growth and 25% of the underdeveloped regions asked to adopt the household responsibility system. However, Zhou's idea received severe criticism from many representatives from other regions and provoked a huge debate over whether the household responsibility system was the right approach to take. In the end, Deng Xiaoping concluded the debate with the observation that household responsibility was a highly complicated and critical issue, and that it was unlikely to reach a simple conclusion.
