The documentary also offer rare glimpses into contemporary China’s political system.
This documentary helps us to get insights from both inhabitants as well as the mayor side as it is comparably not biased. Following the footage into a coherent narrative, we get a better understanding of Geng Yanbo’s intention and residents’ grievance.
