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 U
nited States, Japan, South Korea and the UK.
Witnessing something impossible happen right before your eyes is the root of people’ s love for magic.
“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.
Liu Qian’ s success dated back to his childhood. Born in 1976 in Taiwan, he found himself attracted to a magic toy in a shop when he was seven years old. At the age of 12, he won Taiwan’ s Youth Magic Contest, which was judged 
by the great American magician, David Copperfield.
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.
To refine his performing skills, he has performed on streets, roads and fields for passers-by, policemen and farmers.
“Street shows are the biggest challenge for us magicians. We have to deal with unexpected situations and tough crowds, ” Liu said.
