Last summer I had a unusual experience. It was raining hardly. Because of this the river near my town raised and flooded some of the rice fields. The villagers, included me, went to the dam to make them strong. The soldiers also come to help us. We fought for three days. At last the dam saved and our village was protected from the flood. Though I became very tired after I returned home, but I was very happy. I learned many from the villagers and the soldier. Now we are looking forward to have a stronger dam.
