Professor Dai Wangyun from Zhejiang Yuexiu University came to “Linxia Academy” to have offline exchanges with students at home and abroad who love China's intangible cultural heritage. Focusing on the "Zhejiang Heritage Protection", Professor Dai selected specific cases such as "Qixi Festival", "confinement in childbirth", "snails rice noodle", "Diancui", and "middle-class aestheticization" to introduce the innovation and change of Chinese traditional culture to students in humorous language.
