When I was in primary school, once our math teacher told us: Mathematics is the most important subject since it is the foundation of all science and technology. Without math, there would be no skyscrapers, no cars or planes and no human’s today. You must learn math well because it promotes technology and technology is of top priority.

The interesting thing is, in the next class, our Chinese teacher also said: Chinese is the most important subject, poems and essays depict people’s everlasting emotion. Love, friendship, hatred can all be conveyed by words and language. You must learn Chinese well because literature unfolds human nature and humanism is of top priority.

After the class, my classmates and I were all confused. What is exactly the most important subject? Mathematics or Chinese? Science or humanism?

The confusion has been in my mind for many years. No matter what kind of exam it is, they share the same credit. No matter whether it is science or humanism, each of them plays an essential role. By and by, it seems to me that: They are of the same importance.

My perception, however, changed after a military course in my university. During the class, our teacher said: If one day, 5 billion TNT nuclear warheads exploded, what would be the result? 2 billion people would die. And for the temperature, 10 centigrade would drop. All of us would vanish. This is called “Nuclear Winter”.

We were shocked! And suddenly my math teacher’s voice echoed in my mind: Without technology, there would be no human’s today. But where is our tomorrow? Will it be fantastic? I don’t think so.

Ladies and gentleman, we must be clearly aware that: Compared with high-tech, our humanism becomes more trivial. Warfare destroyed our rosy homeland. Disasters left millions of people homeless. Our Earth is scarred and battered. Without morality, technology is dragging us into darkness. There is only one thing that can save us: humanism.

In 1994, Nash, the Nobel Prize winner, said in the awarding ceremony: I've always believed in numbers and the equations and logics that lead to reason. But after a lifetime of such pursuits, I ask, "What truly is logic?" "Who decides reason? And I have made the most important discovery of my career, the most important discovery of my life: It is only in the mysterious equations of love that any logic or reasons can be found.

Nash’s words struck me. What is the most precious? It must be love, love for ourselves, love for people and love for our mother Earth. And it is the technology guided by our beautiful mind that brings us a bright future.

Finally I’d like to say: It’s great to be great, but it’s greater to be human.
