A 3D realistic Chinese animated story. Passionate newcomer Lin Yu joins the problem-ridden, rundown Yuehuyuan residential community as a property specialist. Senior employee Xu Man warns him that accumulated conflicts over the years have left residents full of distrust toward the property management, advising him to pass the buck and protect himself rather than hitting his head against a brick wall with enthusiasm. However, Lin Yu is unwilling to slack off or lie flat, insisting on facing various disputes with a sincere attitude. Facing tricky problems such as leaking water pipes, chaotic parking, and safety hazards in amusement facilities, he withstands the suspicions and accusations of the residents, refuses to be perfunctory, and follows up and implements every matter on the spot. In the process of communicating and handling problems time and again, Lin Yu uses practical actions to break deeply ingrained prejudices.
