Yunxiang Yan is also a featured subject, together with Tianjian Shi and
Emily Wu, in Chris Billing's 2005 documentary
Up to the Mountain, Down to the Village. From 1968 onwards more than 17 million high school students and young adults were sent "up to the mountain, down to the village" (上山下乡 shang shan, xia xiang) to "learn from the peasants." In the documentary three of those youngsters revisit the remote villages to which they were sent thirty years ago. ==Career landmarks==
