In Daily Life: You will hear 上海话 spoken extensively on the streets, in markets, and in the homes of local Shanghai families, especially among older generations. While all educated people can speak Mandarin, Shanghainese is the language of intimacy, familiarity, and local community.
Decline and Preservation: Due to the national promotion of Mandarin (普通话, Pǔtōnghuà), the use of Shanghainese among younger people has declined. Many children grow up speaking Mandarin as their primary language. However, there has been a recent push for preservation, with some schools reintroducing dialect classes and local media creating content in Shanghainese to foster a sense of pride and cultural continuity.
Connotation: Using a few words of Shanghainese (like “侬好” for hello or “谢谢” for thank you) can be a great icebreaker with locals, showing respect for their culture. However, conversations among fluent speakers can sound fast, clipped, and exclusive to outsiders.
