False cancer diagnosis triggers remote journey
After being told he had lung cancer, which a later X-ray showed was a misdiagnosis, the narrator (paralleling Gao's own 1983 scare and political harassment in Beijing) leaves the city and wanders for months through the forests, villages and minority regions of southwest China and the Yangtze basin. He goes in search of Lingshan, a mountain nobody can reliably locate. The reprieve from death becomes a license to abandon official life and pursue an undefined, personal search.
