Cantonese opera, as a type of traditional performing arts, embodies the essence of Chinese culture. Through its sonorous phraseology, superb acting, unique vocal styles and magnificent accompaniments, Cantonese opera reflects life and society; its plays cover a wide range of cultural aspects, from ethics and morality to history and customs. During the Sino-Japanese war, Cantonese opera became a significant art form to unite the people, evoke nationalistic mood and exude patriotic feelings.
