The modifications of NCQs in response to rural social and economic changes in agricultural villages are explored.
NCQs built during the collectivist agriculture era (1970s) were traditional in style, but with reduced functions.
NCQs built in the agriculture intensification stage (1980 to mid-1990s) played important roles in agriculture production.
NCQs built in the cyclical migration period (mid-1990s to present) are characteristically modern and spacious.
The problems arising from past changes of NCQs and the solutions for tackling them are discussed.
