last summer i have an unusual experience.It was raining hardly.because of this the river near my town rose but flooded some of the rice fields .the villagers,included me ,went to the dam to make them strong.The PLA soldiers also came to help us .we fought hard for three days,On the end the dam was saved and our village protected from the flood.though i became very tired after i returned home,but i was very happy.I learned many things from the villager and the soldiers .I also learned a lots from my unusual experience
