Meng, who is a professor at the Minzu University of China, recalls a trip last year along National Highway 219 from the Guangxi Zhuang autonomous region, across Yunnan province to the Xizang and Xinjiang Uygur autonomous regions, which made her realize just how much she didn't know.

"The world is vast, and the unknown far outweighs the known. The journey itself became a process of mobilizing memories and emotions. When we combine memories, emotions and insights, I believe we gain something more than knowledge — something closer to wisdom," she says, adding that this approach could help address the challenge of teaching in the digital age.
