     Here's an unusual story: a diamond ring was recently found in an egg. The magician, Liu Qian, discovered

it, in front of an audience of millions at CCTV's Spring Festival Gala. Liu's magic tricks have made the

centuries-old art of magic fashionable once again, and made him the hottest magician in China.

     As a seasoned young magician from Taiwan, Liu is popular worldwide for his magic shows. Countries he

has performed in include the United States, Japan, South Korea and the UK Witnessing something impossible

happen right before your eyes is the root of people's love for magic. 

     Liu is known for his interaction with his audiences. He has a unique understanding of showmanship (演出

技巧).

     "It's actually thinking rather than one's manipulation (操作) skills that is more important to achieving a

successful magic show. We think carefully about how to design the shows creatively to make them appear

more interesting." Liu said.

magic toy in a shop when he was seven years old. At the age of 12, he won Taiwan's Youth Magic Contest,

     Yet, Liu never planned on becoming a professional magician. He studied Japanese literature at university

and only hoped to be an amateur (业余的) magician in his spare time. However, his failure to find a proper job

after graduation pushed him towards magic as a career.
