Lessons in the art of teaching

She may already be 90, but Yu Yi is still very much involved in the educational reform process in Shanghai.

The recipient of the People's Educator award from President Xi Jinping this year, Yu has spent more than six decades teaching Chinese classes. Today, she sits on a Chinese education advisory board in Shanghai and is a part-time professor at not one, but four institutions - East China Normal University, Capital Normal University, Shanghai Normal University and Shanghai University.

"It is my calling to be a teacher and to learn to be a teacher," said Yu, stressing the importance of lifelong learning.
