In the 1980s, Zong Lingyu, a graduate of Forestry University, was assigned to the Xinjiang Bazhou Forestry Bureau. Hard scientific research work began in the largest Populus euphratica forest reserve in the country. There he met Hank, a graduate student at Humboldt University in Germany who was volunteering. The windy sand of the desert, the dry Tarim riverbed, more than a thousand miles of walking research work, and the three thousand years of tragic Populus euphratica witnessed their life and work, and they never left each other and stayed together.
