In “Gong Gong with A Headache” released Thursday, Chou raps about the eunuch who has a secret passion for women but “must not touch them.” ‘‘Gong Gong” is a name for court eunuchs in China.

In the music video, Chou dances stiffly like a zombie to the tune of hip hop, dressed in satin imperial court costume.

The singer also wrote the song. He says he was inspired by the popular drama series “The Legend of Zhen Huan” and other court dramas that have captivated audiences in China and Taiwan.
