artist to introduce Peking Opera to an overseas audience, making it popular to the world. For half a century,
Mei Lanfang was a household name in China.

boring eyes. To improve this, he exercised them day after day. He would fly kites and look at them moving
slowly in a blue sky. He also kept pigeons in order to look at them soaring higher and higher until they
disappeared into the clouds. Thanks to his efforts, he managed to transform his dull eyes into a pair of bright
and expressive eyes and win national fame before the age of 20, In over 50 years on the stage, Mei Lanfang
played no less than 100 differents characters in the traditional Peking Opera performance. He completely
