1. My mother, like most people of her time, didn't read many books or go to school. Growing up, I often heard her say that losing is taking advantage, which affected me for most of my life. This does not mean that in order to take advantage, you will suffer, nor does it mean that if you suffer, you will definitely take advantage. This is a philosophy of life and values. When I was young, I used this as an excuse for cowardice and tried to avoid conflict; When I am old, I regard it as a reason to face failure, with less regret and guilt; As an adult, I regard it as a belief far from fame and fortune, and keep my inner peace.

After graduating from middle school, I worked on the farm for five years. I once recommended college students of workers, peasants and soldiers to study in normal colleges, and many people on the farm recommended me. I was full of confidence at that time. But it didn't take me long to know that the last recommendation was another person. I tried to argue, but it didn't change. You can imagine my mood at that time. It took me a long time to calm myself down. Many years later, when I read a passage in Prayer in Nepal, I can still remember those sleepless nights. That passage is: Please give me peace and accept what I cannot change; Give me the courage to change what I can; Please give me wisdom to distinguish the two. Every one of us will encounter things that are hard to accept in our hearts. How to keep a healthy and peaceful mind all the time really requires great courage and wisdom, and we need to experience, comprehend and appreciate. Things in the world are sometimes wonderful. When I face the reality with a peaceful mind and remain optimistic, I will get unexpected surprises in my life. I failed to get into that normal college, but I was lucky enough to catch up with the college entrance examination the next year and was admitted to Peking University.

Let me tell another story when I was studying in America. One day, my tutor brought a toolbox to the laboratory and gave it to me. He said he bought it with his own money. I was surprised. I asked him why he didn't use research funds to buy it. He said that these tools can be used in the laboratory and at home. It is troublesome to buy them with scientific research funds. You might as well buy it with your own money. It's not expensive anyway. Did he suffer? Maybe it is. But in the gray area of the system, he avoided possible doubts and let everyone know more about his personality and values-this is a reliable person and trustworthy.

Students, some people say that universities are cultivating exquisite egoists, but I don't agree that verbal refutation is powerless, and winning trust depends on practical actions. For more than 100 years, Peking University people have always stood in the front line, fighting and struggling for the destiny of the country and the nation with their own strength, no matter when the nation was in danger or when the Chinese nation was greatly revived. Cai Yuanpei, Li Dazhao and Hu Shi ... represent generations of Peking University people who have made unremitting efforts. The same is true of a new generation of Peking University students. We firmly believe in and practice the concept of "honesty and innovation, leading the future" and contribute to the great rejuvenation of the Chinese nation.

5. Peking University students who want to go out from here can stick to their own value judgment and keep the bottom line in any environment. I hope you can face success and failure calmly, face any misunderstanding and doubt gently and calmly, and face injustice and even provocation with patience and restraint; In the face of achievements, I hope everyone can be humble and grateful, face problems, and hope that everyone will never give up and dare to take responsibility. We should never forget in our hearts that a person's character is his most precious wealth; A university, spiritual culture is the most precious wealth; In a country, the values of young people are the most precious wealth. I am convinced that one day, Peking University will be proud of you. Students, during your time at school, there were many shortcomings in the work of our school. I want to apologize to you. Please believe that the leaders and faculty of the school will continue to work hard, shoulder their own mission and responsibility, and build Peking University better.

6. It is difficult for any language to express the mood at this moment. Today, you will leave the campus and embark on a journey. I want to sum up with a few words from Mr. Ba Jin's "Be a Warrior" to encourage you-soldiers are most needed in this era. But such soldiers don't have to carry guns to the battlefield. His weapon is not necessarily a bullet. His weapons can also be knowledge, faith and strong will. It is the "future" that guides soldiers in battle and gives people hope and encouragement. Soldiers will never lose the vitality of youth. Finally, I wish you all eternal youth!
