On May 24 morning, many group members joined a trip to Yuyinshanfang （余荫山房）to celebrate the the successful PhD and MSc degrees defenses of Sun Yue（孙悦）, Su Tao（苏涛） and Huang Chen（黄晨）. Everybody was very cheerful and enjoyed the ancient Chinese tradition of education. Nice pictures always come with the ritual event. This is the second trip of the gorup to Yuyinshanfang, and I have decided, as I announced in the Jun An Hall (均安堂）, we will keep it as a tradition of the group!
On May 10, Sun Yue did her PhD viva, online. The assessment panel includes Professor Chen Yingjun, Tian Chongguo, Zhang Yanlin, Song Jianzhong, Li Jun. As I was at Changsha, I could also only join the event online. Congratulations!
