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

     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

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.
