Why can't tiger people work?

The old janitor, handyman on the construction site, and logistics personnel who cook and deliver water are incompetent due to their age of 6. Life makes it impossible for everyone to recognize a truth clearly. Time and tide wait for no man! Because of the aging, many heavy jobs on the construction site can't be done, and if anything happens, the construction site can't afford it. Life is like a dream. Time flies. When I look back, I am an old man. If I think about it carefully, it seems like yesterday.
