Life is precious to everyone, and everyone's life is only once, so when we are alive, we should all do something meaningful to life. We saw the news that Peng Shilu, the first chief designer of China's nuclear submarine, passed away. He has made great contributions to China's nuclear submarines, especially in the design of our nuclear submarines. We are very sad about his facts, but we also hope that his family can grieve.

First of all, Mr Peng Shilu, the first chief designer of China's nuclear submarine, passed away. Maybe everyone will have their own state of life and lifestyle. In our own life, we will all have our own areas of struggle, and at the same time we will work hard silently and hard. Mr Peng Shilu, the first chief designer of China's nuclear submarine, died. Many people feel sad about his fact, but people will always leave, so we should learn to mourn his death.

Second, he has made great contributions to our country. We live in a happy era. However, this era is also an era of rapid development. Behind this happy era, there will be many people who work hard silently. Try the chief designer of China nuclear submarine. He has made great contributions to our country, especially in nuclear submarine affairs. He made great efforts and energy. He devoted all his energy and youth to the design of nuclear submarines in China. It has made a major breakthrough in the design and research of nuclear submarines in China. Thanks for his contribution, we also hope to learn from his spirit and knowledge and make greater contributions to the motherland.

Time flies, everyone will eventually leave this world. Perhaps many people will feel very sad about this academician's departure, but we should also learn to face our own life. We can all see his contribution to the design of nuclear submarines in China, and we will remember his contribution.
