Jokes describing character actions

The old man repairing the bicycle on the side of the road tremblingly parked an old bicycle on the side of the road. His clumsy body slowly walked to the bicycle basket, and slowly picked up a small bench. Bend down and steady on the ground. A bicycle with a broken chain parked in front of his stall, and a young man called out: "Uncle, repair the bicycle." Before the old man had time to remove other things from the bicycle, he turned around, squatted down slowly, and sat on the bicycle. The body of the stool is slightly tilted forward. A pair of old hands skillfully fiddled with the bicycle chain and pedals. After a while, the fallen bicycle chain was re-tied. Seeing that the car was repaired, the young man took the car and left without looking back. The old man stood up with difficulty, rubbed his dirty fingers on the apron at his waist, shook his head, and turned around again to move the things that had not been taken off the car rail.
