Let Out A Yawn 呵%^~欠

Yawning is driven by internal physiological factors, typically caused by drowsiness, and I am interested in the contagious aspect of yawning.

Starting from December 2008, I invited people interested in this activity to yawn in Shanghai, Berlin, Florence, and Beijing. The documentation methods include video recording, photography, hand-drawing, and this project is still ongoing.
