When I first heard Mr. Cardiff's speech, I thought at first, Wow, someone can make such an interesting speech. The interesting speech contains a lot of knowledge points. How did this man do it? When I learned that Mr. Cardiff was born in 1990, I admired him a little more. His college life is so inspiring that few people can reach his efforts. I can't believe that such a young man has achieved so much. After I attended Mr. Dianfu's class, I found that Mr. Dianfu is a very sincere person. He taught us all his knowledge carefully. Every time I communicate with Mr. Cardiff, I feel that I am growing. Every time I quietly record the contents of the exchange, I am very grateful to Mr. Cardiff for his guidance. Teacher Dianfu is like a bright lamp, which helps me to illuminate the direction.
