     Adrian's "Amazing Race" started early when his parents realized that he, as a baby, couldn't hear a thing,

not even loud noises. In a special school for the hearing-impaired (听觉受损的), he learned sign language and

got to mix with other disabled children. However, the sight of all the disabled children communicating with one

another upset his mother. She wanted him to lead a normal life. So after speaking to an advisor, she sent him to

private classes where he learned to read lips and pronounce words.

     Later on, Adrian's parents decided to send him to a regular school. But the headmaster tried to prevent them

from doing so, saying regular school couldn't take care of a special needs students. His parents were determined

to take the risk and push him hard to go through his work everyday because they wanted to prove that, given

the opportunity, he could do anything. Adrian made the grade and got accepted. It was a big challenge. The pace

(节奏) was faster so he had to sit at the front of the class and really pay attention to the teacher, which wasn't

always easy. But he stuck to it and did a lot of extra work after school.

     The efforts made by Adrian and his parents paid off. Adrian graduated with good grades and got into a top

high school. He also achieved a lot in life outside school. He developed a love for the outdoors and went to Nepal

to climb mountains. He even entered the World Yacht Race 05/06-being the first hearing-impaired Asian to do so.

     But none of these achievements would have been possible without one of the most important lessons from

his mother." "If you believe in yourself and work hard, you can achieve great results." She often said.
