Li Wei's College Dream

Li Wei, a 22-year-old young man is named "Strong Brother" by netizens(网友). He walked on his knees all the way to the 2011 national college entrance examination (高考) room. He was born in a poor family in Shanxi province. But unluckily, a traffic accident took away his legs when he was only 3 years old. His life has changed since then. Without feet, he had to spend most of his time practicing walking on his hands and knees. Everybody who sees Li Wei for the first time is surprised to see that he can easily play tennis or climb up stairs without feet. Some people even think he still has feet, but has short legs.

With hard work, Li Wei finished all his school study. In 2011, he became a college student in Chongqing Normal University. Now he  has been enjoying his college life. And he received a new pair of artificial legs (假肢) from China Disabled Person's Federation (残联).

He likes the popular song which says "I know my future is not a dream, I will live happily for every minute of my life. My future is not a dream. My heart moves with the hope…" Follow your dream, and it will come true one day.
