In the winter vacation, I paid a visit a mountain village in a suburb of Luoyang. No sooner had I got off the bus when I was greatly surprising to see all the changes. It was far better than I had been expected. Now every family can drink cleanly running water. The villagers needn’t carry water himself any more. Firewood is no longer used for cooking. Marsh gas, a new cheap clean energy, make it very convenient to cook and light. As all the families have color TV set, they can enjoy plays at home. It impressed me most was that the best building in a village was the school. I hope the mountain village will become better and better.
