Each of the first few numbers was more elaborate than the last, teeming with acrobatic dancers, awash in jewel-toned silks, swelling to the anthemic strains of the orchestra. It was the opening night of Chinese New Year Splendor, a music and dance production that began at Radio City Music Hall last week.

Then the lyrics to some of the songs, sung in Chinese but translated into English in the program, began referring to “persecution” and “oppression.” Each time, almost at the moment a vocalist hit these words, a few audience members collected their belongings and trudged up an aisle toward the exit.

Before long came a ballet piece in which three women were imprisoned by a group of officers, and one was killed. At the end of the number, more members of the audience, in twos and fours and larger groups, began to walk out. At intermission, dozens of people, perhaps a few hundred, were leaving.

They had realized that the show was not simply a celebration of the Chinese New Year, but an outreach of Falun Gong, a spiritual practice of calisthenics and meditation that is banned in China. More than three years after flooding city corners and subway stations to spread the word about the Chinese government’s repression, Falun Gong practitioners are again trying to publicize their cause. Only this time, it involves costumed dancers and paying audiences in that most storied of New York concert halls, Radio City.
