These doctors seated in the audience are virtuosos in their fields, so Yang Ping speeds up the pace of the lecture.
There's a large white board on the podium. Yang Ping simply tells Song Yun to turn off the projector, pulls all the curtains of the meeting room open, abandons the use of the projector, and resorts to the white board for teaching.
For every step he introduces, Yang quickly sketches on the board; his accelerated sketching pace is astounding.
The quality of the sketches further astonishes everyone. One black marker, using two ends of varying thickness, can produce extraordinarily accurate and beautiful sketches, which are much more detailed and aesthetically pleasing than those found in textbooks.
After each segment, Yang Ping erases the sketch and starts drawing a new one. Sketching seems to be effortless for him.
These illustrations demonstrate the principles of surgery, anatomical basics, and the procedures of each step.
