(Airdate: January 27, 2025) We’re on a stretch of paved highway that runs the length of theGansu Corridor, paralleling the Great Wall. Wuwei is behind us, and before us is the town of Zhangye. The only sign of civilation in between is the town of Shandan, and it’s not much of a sign. Shandan’s only claim to fame is a New Zealander who came there to set up an arts school.
