Xiao Shenyang was born in a poor peasant family which is in difficult family conditions. His real name is Shen He. He is an actor. He is good at Er Ren Zhuan. He learned acts, following Zhao Benshan. During the school life, he was very active in many activities. He looks like a simple man, but he never stops pursuing (追求) his artistic aspiration (渴望). More and more people like his style of performance, and we hope he can make great progress in the future. Liu Qian is a young magician from Taiwan. At the age of 7, Liu saw a cute magic toy in a shop. At that moment he began to love and decided to learn magic. Liu didn't go to any magic school. He practiced tricks every day to improve his skills, until one day he was able to put on a show for his class. He saw the surprise on everyone's face, and he felt it was cool.
