A high school senior who risked his life to save a classmate from being hit by a truck underwent another surgery on Tuesday morning to have a toe on his left foot amputated.

Gong Yuben, 18, a student at Zaozhuang No 2 Middle School in Shandong province, lost most of his right leg in an accident on Nov 3.

Gong was riding on the back of an electric bicycle driven by classmate Chu Hao when a truck suddenly drove toward them.
