Take people’s communication for example. In the past, our grandpas had to ask someone who could write for help when they wanted to contact their relatives or friends. As for our fathers, they kept in touch with each other by writing letters by themselves. With the development of science and technology, we can communicate with each other anytime and anywhere by mobile phone.

As a new generation, we are so lucky living in the new century. We’re proud of our country and its achievements. So we should cherish the happiness of today’s life. Meanwhile, we should put more effort and make more contributions to our beloved motherland. We believe she will become stronger and stronger.
