Caochang Community lies within the Qianmen area of Beijing. Li Zheng is the director of the local residents' committee, and he has recently overseen the construction of a public charging shed for electric bicycles. Keen to get some feedback, he has been going door-to-door, giving all the residents the chance to say what they think about the new facility. Based on the diverse opinions he has heard, he has managed to draw up a new set of regulations for using the shed.
