We played a game based on the description of Zhong Zhi provided here. Had three teams. Two finished quickly; the third took considerably longer. This game is simple: no set up, no long discussion afterwards. teaches rather quickly that if we each go our own way, work will be duplicated and some work missed, but if we communicate and collaborate, we can produce as a team what no one can as an individual. we scheduled it at the beginning of the workshop to get people moving and talking.
