He only finished fourth in this year's Super Boy talent show. But it didn't stop him capturing (俘获) the hearts of thousands of fans. He can hit high notes with ease. And he is very modest. Zhang Jie,25,shed(流) sweat and tears all the way through the competition, but he never gave up.

“No matter how life treats him, he always fights back bravely ,”said Wu Chunyan, a Senior 2 student in Hubei.“He has never lost his dream of being a singer.”The road to fame is always rocky, and Zhang is no exception. As a college student he was majoring in tourism. He was considering becoming a tourist guide after graduation until he entered a singing competition.

His life changed after he competed in My Show. He won first place and signed with a record company.“I was very excited and regarded it as a way to take me closer to my dream,” he said. But the company gave him little money to make music and slowly began to ignore him. Zhang even borrowed money to buy costumes.“Life has its ups and downs. But the tough (艰难的) reality only makes me stronger,” he said.

He forgot he was once a champion of a talent show and joined Super Boy. His decision got support from his family who worked hard to make ends meet. His mother sold rice noodles on a street in his hometown, but she said she would “support him forever.”

“I have the dream to buy a large house for my parents, where my mom can get a large window sill (窗台) to grow flowers,” said Zhang.
