Wearing of cartilage in the legs is a common ailment among teachers.
Especially for older teachers from earlier years, due to prolonged standing, the pressure on the meniscus of the knee becomes uneven. Over time, the cartilage wears away and degeneration occurs.
This disease is most noticeable in people over the age of sixty-five.
Yet Li Yiming appeared to be under fifty.
To be afflicted with such a condition at his age, and to the extent of difficulty walking, was enough to indicate that he had been teaching for a long time and that he had taught many hours of classes.
So, after hearing his story, Wang Chen held even more respect for him.
Wang Chen looked at him respectfully and then squatted in front of him, raising his hand to grasp his knee.
Li Yiming was somewhat baffled by his actions.
However, just as he was about to ask, a comforting warmth emanated from Wang Chen's palm pressing on his leg.
