This 18-year-old boy has carried his friend to class for 3 years

Xie Xu -- an 18-year old high school boy who lives in China -- has a very touching reason behind carrying his 19-year-old friend Zhang Chi to school for the past three years.

Zhang Chi has muscular dystrophy, and walking is often difficult for him, so Xie Xu carries his friend from his dorm to class. He also brings him his three meals each day, and both of the students are in the top of their class at school.

Guo Chunxi, the vice headmaster at the boys' school said, "The story of the two students is so inspiring and touching."
