One day, Ma Haigang, on a sudden whim, went on patrol in the building. Bored, Ma Haigang started walking up the stairs, wanting to see if there was any problem anywhere.
But as he reached a certain floor, Ma Haigang heard a strange sound.
At this moment, Ma Haigang was actually using the fire escape stairs. Ma Haigang found it puzzling since these stairs usually had very few visitors. He was curious and quietly continued upward.
Then, at a turn in the staircase, Ma Haigang cautiously poked his head around and instantly widened his eyes.
He saw a man standing there at the corner of the stairwell, facing the angle between two walls, doing something mysterious. But Ma Haigang quickly saw clearly that there was a woman crouching in front of the man.
Well well!
Ma Haigang wasn't some naive young man; he had frequented those shady parlors and had his share of dalliances with ladies of the night, so he immediately understood what was happening.
