The event, organized by China Cultural Center in Paris, has seen six local opera troupes from Hebei, Jiangsu, Jilin, Fujian and Guangdong provinces, showing to Parisians scores of traditional programs of Chinese operas. Chinese theatric art is not novel to French people. Over past decades in the history of modern China, Chinese opera masters, in particular, Peking opera singers, visited Paris many times and made traditional Chinese opera known to French people. For example, when visiting Paris half the century ago, master Cheng Yanqiu gave lectures on Peking opera, the first Chinese opera genre that was introduced to French people.展开更多
