Having traversed rivers, lakes, seas, and even returned from overseas, the alumni gathered on Xikang Road and strolled through the Jiangning Campus, fulfilling their 20-Year Reunion and renewing their camaraderie. The school's Party Committee Secretary Lou Jian, Dean Wang Yuan, Deputy Deans Zhao Lanhao and Yu Xiaodong, former Party Committee Secretary of the School of Water Conservancy and Hydropower Engineering Yu Dahuai, former class advisors Shen Changsong and He Qifang, and former counselor Sun Cuiqing, along with the returning alumni, participated in a teacher-student exchange session. The session was hosted by Lu Jianhui, a former class monitor of the 2005 Water Conservancy Engineering cohort.
