Because it's far from the provincial capital, Yungang has that sense of "high sky and remote emperor." Although the cadres in Yungang aren't as rebellious as those in some districts and counties of Binjiang, when it comes to implementing superior directives, they're not as effective as the Binjiang cadres, and there's no comparison with those from Guzhou and Wuxi.
