Chinese Buddhist Music Catches Audience in HK
中华佛教音乐吸引香港听众

The Hong Kong Cultural Center in Victoria Bay was packed on Thursday night, and loud applause periodically echoed through the neon lit sky. It was not rock music nor was it pop—it was traditional Chinese Buddhist music that made an instant hit in the modern metropolis.
Hong Kong is the fourth leg of the Buddhist music performance tour by a troupe consisting of more than 130 monks from the Chinese mainland and Taiwan. And this is also the first time monks from across the Taiwan Strait had jointly set up a troupe to perform, on global stages.
Crowds of Hong King residents were lining up at the local port waiting to welcome members of the troupe who were sailing in from Macao, where they had just ended another successful performance on Wednesday night.
The monks returned the enthusiasm of the residents with a powerful performance. Almo
A. The troupe will offer three more performances after the Hong Kong event.
B. There will be another religious activity in Hong Kong after the music performance.
C. The troupe will continue its tour to North America．
