At 8:15 in the morning, on the third floor of the art building of Qiming Middle School, a key middle school in the city, the sun shines through the floor-to-ceiling windows, casting grid-like spots of light on the floor. Weismode stood in front of the easel, holding an HB pencil in his hand. The tip of the pen slid gently on the sketch paper, outlining the light and dark boundary of the student's study "Still Life in a Clay Pot".
