Shanghai language used Wu Chinese
Language
The vernacular language spoken in the city is Shanghainese, a dialect of the Taihu Wu subgroup of the Wu Chinese family. This is different from the official Chinese dialect, Mandarin, which is mutually unintelligible with Wu Chinese. Modern Shanghainese is based on other dialects of Taihu Wu: Suzhounese, Ningbonese, and the local dialect of Songjiang Prefecture.Prior to its expansion, the language spoken in Shanghai was subordinate to those spoken around Jiaxing and later Suzhou, and was known as "the local tongue" (本地闲话), which is now being used in suburbs only. In the late 19th century, downtown Shanghainese (上海闲话) appeared, undergoing rapid changes and quickly replacing Suzhounese as the prestige dialect of the Yangtze River Delta region. At the time, most of the city's residents were immigrants from the two adjacent provinces, Jiangsu and Zhejiang, so Shanghainese was mostly a hybrid between Southern Jiangsu and Ningbo dialects. After 1949, Putonghua (Standard Mandarin) has also had a great impact on Shanghainese as a result of being rigorously promoted by the government. Since the 1990s, many migrants outside of the Wu-speaking region have come to Shanghai for education and jobs. They often cannot speak the local language and therefore use Putonghua as a lingua franca. Because Putonghua and English were more favored, Shanghainese began to decline, and fluency among young speakers weakened. In recent years, there have been movements within the city to promote the local language and protect it from fading out.
