In order to learn Lei Feng's spirit, enhance everyone's awareness of environmental protection and cherish our common homeland, on the morning of March 10, 2018, a series of volunteer activities on Lei Feng's theme of environmental protection, sponsored by the Furong League Committee and Donghu Street of Furong District, Changsha City, were launched on the banks of Liuyang River. The international students of HUNAU were given the banner of “International Team of Blue Sky Protection Volunteer”. They would organize Lei Feng's volunteer activities periodically with the volunteers of Dongsha Community Party Branch and Mingzhi Public Welfare Association.

International students and volunteers worked together and cooperate closely. This event not only enhanced their awareness of eco-environmental protection, but also learned the spirit of China's Lei Feng's dedication to society. They contributed a lot to the blue sky defense war.
