Finally, I want to end today's speech with a story: there is a tombstone in the basement of Westminster Abbey in England, which reads: When I was young, I dreamed of changing the world, but when I matured, I found that I could not change the world. So, I shortened my vision: then change the country. But when I got old, I found that I had no ability to change my country at all. Therefore, my last wish is only to change my family, but it is also impossible. When I was lying in bed dying, I suddenly realized that if I just started to change myself, maybe I could change my family. With the help and encouragement of my family, maybe I can do something for my country. Then who knows, maybe I can change the world! Therefore, the most important thing for each of us is to learn how to change ourselves. My speech is over, thank you.
