Earlier this week, my wife Pele and I crouched beside a small fire, a handful of miles from the Chinese town of Yungshuo.
Keeping us company was a school principal and an elementary teacher. The principal added charcoal to the wok-like pit as carbon monoxide rose from the flames.
We weren’t on a winter camping trip. Instead, we were in a Chinese school’s administrative building, which doubled as a teacher’s staff room. Pele and I were there as part of a service trip with 20 tenth grade students from Singapore American School.
