International Symposium for Young Scholars on Global Change and Biological Acclimation was held in Henan University from January 11^th to 12^th, 2021. The symposium was hosted by HENU and supported by School of Life Sciences and International Joint Research Lab for Global Change Ecology. 4 international experts from United States, Finland and Canada along with more than 200 people from 20 universities and research institutes attended the event. Mao Liqun, Director of International Affairs Office, Hu Binbin, Vice Director of Institute of Science and Technology, Zhang Lixin, Dean of School of Life Sciences, Zhao Haipeng, Vice Dean of School of Life Sciences，Li Zhifang, Assistant Dean and Director of Talent Training and International Affairs Office of School of Life Sciences, Professor Han Shijie, and Professor Li Guoyong attended the opening ceremony. The meeting was presided over by Zhao Haipeng.

Mao Liqun delivered a welcome speech and introduced the development of both HENU and Ecology in our university. She also looked forward to facilitating insightful conversation among conference participants which, without a doubt, will give to new and exiting ideas and approaches for development of Ecology.
