The green guardian

In order to protect the forest, the couple have to live apart from their family. They only had one parent conference for their daughter between her elementary school years and university graduation. Whenever he mentions her daughter, Liu always feels indebted. They value the forest more than anything else. "Fire prevention is our priority. Only by protecting this place can we be worthy of the trees planted by the predecessors,"Liu says.

Since the establishment of the forest farm, more than 20 couples have guarded the watchtower, and there has been no fire reported in the farm.

After more than half a century of development, Saihanba today is not only a "green Great Wall" for windbreak and sand fixation, but also a timber source for wood processing enterprises.
