Peng Si, a 22-year-old college student, has moved many Chinese with his filial piety as he saved his sick mother's life by donating 60 percent of his liver to her during an organ transplant surgery.

"I didn't think too much. My mother gave me my life. When her life was in danger, I had to do something to save her. It's the only thought I had after hearing of her illness. I never thought of how dangerous it could be," said Peng.

Peng was born in Guangzhou, south China's Guangdong Province. Due to his good performance at school, he became an exchange student for academic study in the United States when he was a third-year student in the senior middle school. In 2008, Peng was admitted into the Department of Accounting at the University of Northern Colorado in the United States. After receiving a phone call from his father about his mother's illness, he immediately flew back home to donate his liver to his mother, who was suffering from fulminant hepatitis. With 60 percent of his liver transplanted during a successful operation, he has saved his mother's life.
