Research team members Liu Xin, Cheng Ming, Wang Sai, Guo Shuwen, Zuo Xuan Zan and Professor Leyong Wang participated in the 18th Macrocyclic Chemistry and 10th Supramolecular Chemistry Conference held at Hunan Normal University in Changsha (August 25-28) day). During the period, I visited Hunan Normal University and Hunan University, and visited Juzizhoutou, Yuelu Academy and Yuelu Mountain. Thanks to the host, Professor Song Jianxin and colleagues from the School of Chemistry of Hunan Normal University for their meticulous organization and warm hospitality. In his youth, Mao Zedong studied and worked in Hunan No. 1 Normal School from 1911 to 1923. He often went to Zhoutou to fight the waves with his classmates and friends. In 1925, Mao Runzhi swayed the popular poem Qinyuanchun·Changsha and issued I wonder in this world so vast and dim, Who decides who will sink or swim”. (When, students in the flower of our age, Our spirit bright was at its height, Full of the scholar’s noble rage, We criticized with all our might. Pointing to stream and hill, Writing in blame or praise, We treated like dirt all mighty lords of olden days. Do you remember still, Swimming mid-stream, we struck waves to say. That boats speeding their way?
