Wang Zhongtao hastened to explain: “This was approved by a Group leader.” Wang Wenbiao did not accept his explanation and chided, “No one has the right to approve it! It’s strictly forbidden in the restoration area. Otherwise, the trees we planted with so many hardships won’t be preserved.”Since the forests were very large, it was impossible to rely on one company to prevent logging and fire. In this case, forest police were imperative. Luckily, with the support of the government, a police station was soon set up to help Elion safeguard the forests. Without the strict enforcement of the “no logging” rule, the sand control achievements could hardly be maintained, as the old saying goes “if building a forest takes generations of arduous effort, destroying it needs only one day”.After spending four years building 242 km-long asphalt roads and planting over 1333.3 km2 of forests consisting of licorice plants, desert willows and poplars, which cost one billion yuan and involved 100,000 local people, the forest belts along the Yellow River were preliminarily established.
