Bonus Episode: The old man and the desert

The Mu Us Desert, one of the four major deserts along the Yellow River, was once a lifeless expanse. Now, it’s turning green, thanks to decades-long efforts by the locals to combat desertification. In this episode, we meet a centenarian who spent his life planting trees in Jingbian, the first county in Shaanxi Province to stop discharging silt into the Yellow River.
