How do you understand "Green Miracle" in the title? The "Green Miracle" refers to the incredible transformation of Saihanba. It changed from a barren wasteland in the 1950s into a large man-made forest with beautiful grasslands. This is considered a miracle because the natural conditions were extremely harsh (low temperature and strong wind), making it very difficult to plant trees, and most young trees died at first. Despite these difficulties, the foresters' hard work eventually turned the wasteland into a lush "Green Great Wall." Think and share 2. How did the foresters turn Saihanba from a wasteland into the "Green Great Wall"? They achieved this through perseverance and hard work. Although the first two years were difficult and most trees died, the foresters never gave up. They worked hard year after year, tried new ways to plant and take care of the trees, and continued their hard work day and night. Later, more and more young people joined them. Eventually, the young trees grew into tall trees and green forests.
