Major Wu dialects include those of Shanghai, Suzhou, Wuxi, Wenzhou, Ningbo, Hangzhou, Shaoxing, Jinhua, and Yongkang. Wu speakers, such as Chiang Kai-shek, Lu Xun, and Cai Yuanpei, occupied positions of great importance in modern Chinese culture and politics. Wu can also be found being used in Shaoxing opera, which is second only in national popularity to Peking opera; as well as in the performances of the popular entertainer and comedian Zhou Libo. Wu is also spoken in a large number of diaspora communities, with significant centers of immigration originating from Qingtian and Wenzhou.
