This book chronicles a magnificent expedition undertaken by the 'Zhejiang University Student Volunteer Green Camp' in the summer of 2001. Driven by a spirit of pure devotion, a group of university students journeyed by bicycle for over twenty days, traversing a vast expanse from the Fuchun River and Mount Huang to Qiandao Lake and Lake Tai. This mission was more than just an in-depth scientific survey of natural landscapes; it was a tempering of youth through the crucibles of discipline, willpower, and collective collaboration. Through the process of monitoring water quality and engaging with local communities, the team members underwent a profound transformation-evolving from grassroots environmental practitioners into passionate messengers of green ideals.
