In the hinterland of Mu Us Desert in April, there was a chill in the morning breeze. At dawn, 98-year-old Guo took his 7 1 year-old son Guo Xihe and his 49-year-old grandson to pack up the "guys" and prepare to enter the sand. They should water the newly planted saplings before the sand temperature rises. His great-grandson Guo Tao heard the sound, got up from the kang, got dressed and set off with his elders in 1984. I heard that Jingbian county began to transfer barren hills and sand to households and contracted management. Guo, who has more than ten years' experience in forest protection, decisively contracted 45,000 mu of desert sand more than 0 km away from home/kloc-0. He took out all his savings 1200 yuan, borrowed another 4,000 yuan, bought 50,000 saplings, moved into Shawozi with his family, and started a hard struggle against the desert for more than 30 years. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Through the continuous efforts of four generations, the long yellow sand of 45,000 mu in the past has now become a lush forest. _ Hum: "My grandfather, grandfather and father all have indomitable tenacity. Generations of our family have used this tenacity to lock this flowing sand dune. "
