The 93-year-old professor from Xi 'an returned to the podium: What's the point of life without lectures?

Recently, a video of an old professor explaining the couplets of metrical poems caused a heated discussion in Weibo. This old professor named Pan Dingkun is 93 years old this year. Although he is white-haired in the video, his voice is still powerful. In the School of Science of Xi University of Architecture and Technology, Pan Dingkun taught advanced mathematics all his life. On May 24th, he told reporters that although he was a math teacher, he had always had a strong affection for China's poems because of the influence of private school culture since childhood. In math class, he also quoted Li Yu's poem "When are the Spring Flowers and the Autumn Moon". Explain the relationship between finite and infinite for students.

Although he is 93 years old, Pan Dingkun didn't invite an assistant to give a lecture. He carefully prepared for the first class alone for several months. In Pan Dingkun's view, all kinds of poetry appreciation books popular on the market now only explain the basic meaning of poetry to students, but the "core technology" of poetry writing rules is not taught to students.

The reporter asked, you are old now. Does your family support you to continue your lectures? Pan Dingkun said that my children are very filial. They are afraid that something will happen to me, so I told them that nothing will happen to me. Don't be afraid. For me, one more class now makes me feel particularly meaningful, and I think it can prolong my life. I think my life is meaningless without classes. When I stand on the podium, I feel very energetic.
