Protecting magic secrets can be tricky proposition

Internationally renowned magician Lu Chen is a staple of the annual Chinese New Year's Gala, his illusions inspiring many to seek out the secrets behind them.

This is what has Lu worried, the magician said.

One of the nation's most popular acts, Lu has performed his magic tricks in the annual gala four times. But he has grown hesitant to return to stage this year because his illusions lack proper legal protection.
