PCOS was established by a group of dedicated individuals in February 1999 and incorporated in Pennsylvania as a non-profit organization. PCOS is the only organization in our region devoted to the study, teaching, and performance of Beijing opera. We are fortunate to have a group of internationally known artists, such as Ms. Li Shuyuan, a founding member of the organization. Ms. Li has been our Artistic Director since our inception. Mr. Liu Zhenguo is our Music Director and our chief musician.
The mission of PCOS is to promote cultural diversity and exchange, to enrich the cultural lives of the Asian/Chinese American community and the general public, to enhance the appreciation and understanding of Asian arts and cultures, to preserve and promote the cultural heritage of the Chinese community, particularly, the folk treasure of the Chinese Opera (Beijing Opera). PCOS attempts to achieve the above goals through means of educational/apprenticeship programs, organizing and participation in performances and cultural events.
PCOS has bi-weekly classes at the Folk Arts & Cultural Treasurer Charter School in Chinatown, individual lessons in Northeast Philadelphia. Activities include group and individual children and adults classes on all aspects of Beijing opera.
