When I was very small, my grandpa liked to tell me his tough year and I liked to listen to him. At that time, wars were everywhere, people ran away for keeping alive. My grandpa was so hungry all the time because he had no food to eat. People had the very hard life before the found of new China. Today, Chinese economy develops so fast, we live the good life, we are no longer struggle for the hunger. Thanks to our great predecessors, they build the road for us. We enjoy the peaceful life and I know it is not easy to achieve. My grandpa educates me not to waste the food and I keep his words in my mind. Peace is the main theme of today’s world, we can chase our dreams and enjoy our life, but we must remember the contribution which is from our predecessors.
