云监工

Meaning

The cement truck at Wuhan Huoshenshan/Leishenshan construction sites. It's the truck carrying a long tank on its back. Obviously, since it spits out mud/cement, using the Japanese "onii-chan" (big brother) sound, it's called "Ounijian" (sounds like "vomiting mud sauce")! Also called "Songhuizong" (delivering ash ancestor).
