City cleaners to clear clogged drains 
Aerial mechanic, like Spider-Man General 
Elephant dung staff pick 
Human toilet, you dare to use it? 
Human vertical target, high-risk operations 
Medical check-ups 
This radiation, this density, shocking 
The most troublesome porter 
Underground workshops abroad 
Hot day, and had to wear costumes so thick, in order to survive is not easy
