The cardboard box hit the revolving door on the first floor of Shengshi Building.
Scattered folders, a few cheap ballpoint pens, and a half-pack of uneaten soda crackers rolled down the marble steps to the floor.
The rubber stick in security guard Lao Li's hand knocked on the glass door, making a dull banging sound.
"Hurry up and leave. Mr. Wang has told you that you are not allowed to set foot in this building from now on."
Lao Li, with his beer belly bulging out, pointed condescendingly at Jiang Nan's nose.
"If you don't leave any longer, I'll call the patrol."
Jiang Nan squatted down.
Pick up the ballpoint pens that have rolled away one by one and throw them into the cardboard box.
Rent is due next week.
