Li Yizu himself is a role model according to his own standards. In his 70s, he is still providing his expertise to documentary teams and geological exploration teams and sharing his knowledge with children. He says he is a man who always stays foolish and stays hungry, since he believes the best scenery of life just comes from endless climbing which will take a man to new heights.

"People always say I am energetic when going outside. I have a special feeling about working in the field. The picturesque landscape of our country is very inspiring. To tramp over hills and dales can be hard, but I never want to give up. Sometimes I feel tired and don't want to continue climbing, but once I climb up, I think everything is worth the effort."
