This Old Guy's No One to Mess With

This Old Guy's No One to Mess With Plot:

Everyone in the neighborhood teases Old Zhang as "Laodeng"—a retired man who walks around daily and runs errands for neighbors, always treated as a "soft persimmon with no temper". Until the new property manager, to hit the performance target, arbitrarily deducts elderly owners' property fees and wants to tear down the community bulletin board in public, crossing Old Zhang's red line. He immediately reveals his identity as a former senior criminal police officer, accurately points out the property company's account loopholes, and exposes the manager's embezzlement secret, leaving the arrogant property manager speechless. It turns out that this seemingly ordinary old man is the tough role no one in the whole community dares to mess with.
