After precarious work, trees transform rocky faces

Now, the mountains have taken on a new look, with trees rooted deep. They are blooming and flourishing.

Lin said he used to make a living by planting, but when he saw the great changes in the mountains and how afforestation had improved the farmers' lives by conserving the soil and water, he felt a great sense of pride.

"The longer I plant trees, the greater attachment I have for the woods," he said, noting that the toughest part of the job is done. Later management work, such as weeding and pruning, is much easier. With trees, the cliffs have become firmer and safer.

"I have a sound body," he said. "But even if I can't plant trees in the future, I'll let the youngsters know about the benefits."
