　　Professor Xu Wenyao, a researcher at the Institute of Geology and Geophysics of the Chinese Academy of Sciences, a professor and doctoral advisor at the Graduate School, and the vice chairman of the Chinese Committee of the International Union of Geomagnetism and Aerospace Physics, delivered a lecture titled "Starting from the Wandering Earth". Drawing on his profound knowledge and extensive experience, he presented in a concise, vivid, humorous, and witty manner, revolving around three major questions: "Why did the Earth escape from the sun? How did it escape? Where did it go?"
