At 4,000 meters, 80-year-old couple retraces the Long March

At Jiajin Mountain Pass in Sichuan, 4,114 meters above sea level, Mr Feng, now in his 80s, sang an excerpt from the Long March Suite. "We came up by car, but back then, the Red Army soldiers walked up, along horse trails." For him, the journey is a reminder of the sacrifices that made today's life possible. This year, as China marks the 90th anniversary of the Long March's victory, join Unboxing China to retrace the route and meet those who keep its spirit alive.
