Yunqicheng Underground Pipeline Intelligent Maintenance Record

Photos of workers inspecting urban underground pipe networks. Those figures wearing gas masks and protective clothing suddenly made me realize: behind the convenient urban life we ​​enjoy, there is a group of people silently guarding us in the most dangerous spaces. Future technology may allow robots to replace them, but the reverence for life and persistence in duty will never go out of style. I dedicate this article to all those who protect this city in invisible places.
