I have a positive evaluation of his life. I think he is a person who constantly creates his own value for the society, and never asks for the return of the country and the people in the society. All his actions are actually very selfless, all for the development of the country's cause, and all are very powerful forces to promote the development of the country. I think this is a virtue of the older generation of scientists, who can stick to their posts and create their own value for the country under any difficult circumstances. Without such people, the development of our country will certainly face greater difficulties.

Life is very low-key

Although he has a high position in the society and has become an academician of the Chinese Academy of Sciences, he is still very low-key in his life, never wearing famous brands and living a simple life. Even though the Chinese Academy of Sciences gives generous treatment every year, he will still use the money for the development of the national cause. This is a move that few people can make, but for him, it is a belief he accepts. He believes that only the progress of the country can make everyone live a good life.

Outstanding contribution

My most intuitive impression of him is that he has made great contributions to remote sensing science in China, which directly pushed our country to a relatively advanced position in the world. It already has its own position in the world, which can be compared with American technology in this field, and even some sub-sectors are more developed than American technology, which is entirely due to his contribution.

Our country has made rapid progress in recent years, which is completely inseparable from the efforts of this generation. In those years, if these people hadn't overcome difficulties and contributed their own strength to China's science and technology, our country wouldn't have developed so smoothly, and the country and people would never forget them.
