Wu Language is a major Chinese language group primarily spoken in the eastern region of China, particularly in Shanghai, Zhejiang, and parts of Jiangsu. It is one of the most widely spoken Chinese dialects, with millions of speakers. Wu has several local varieties, including Shanghainese, which is the most recognized form. The language is known for its distinct phonetic features, including a rich tone system and a variety of vowel sounds. Unlike Mandarin, which has four tones, Wu languages can have up to seven or eight tones, making it unique and complex. Wu is also characterized by its own vocabulary and grammar, differing significantly from other Chinese dialects.
