Differentiating Between Shanghainese and Mandarin

Since Shanghai is in the People's Republic of China (PRC), the official language of the city is standard Mandarin Chinese, also known as Putonghua. However, the traditional language of the Shanghai region is Shanghainese, which is a dialect of Wu Chinese which is not mutually intelligible with Mandarin Chinese.

Shanghainese is spoken by about 14 million people. It has retained its cultural significance for the Shanghai region, despite the introduction of Mandarin Chinese as the official language in 1949.

For many years, Shanghainese was banned from primary and secondary schools, with the result that many young residents of Shanghai do not speak the language. Recently, however, there has been a movement to protect the language and to reintroduce it into the education system.


Shanghai is the largest city in the PRC, with a population of more than 24 million people. It is a major cultural and financial center and an important port for container shipments.

The Chinese characters for this city are 上海, which is pronounced Shànghǎi. The first character 上 (shàng) means "on", and the second character 海 (hǎi) means "ocean". The name 上海 (Shànghǎi) adequately describes the location of this city, since it is a port city on the mouth of the Yangtze River by the East China Sea.

Mandarin vs Shanghainese

Mandarin and Shanghainese are distinct languages which are mutually unintelligible. For example, there are 5 tones in Shanghainese versus only 4 tones in Mandarin. Voiced initials are used in Shanghainese, but not in Mandarin. Also, changing tones affects both words and phrases in Shanghainese, while it only affects words in Mandarin.


Chinese characters are used to write Shanghainese. The written language is one of the most important factors in unifying the various Chinese cultures, since it can be read by most Chinese, regardless of their spoken language or dialect.

The primary exception to this is the split between traditional and simplified Chinese characters. Simplified Chinese characters were introduced by the PRC in the 1950s, and can differ greatly from the traditional Chinese characters still used in Taiwan, Hong Kong, Macau, and many overseas Chinese communities. Shanghai, as part of the PRC, uses simplified characters.

Sometimes Chinese characters are used for their Mandarin sounds to write Shanghainese. This type of Shanghainese writing is seen on Internet blog posts and chat rooms as well as in some Shanghainese textbooks.

Decline of Shanghainese

From the early 1990s, the PRC banned Shanghainese from the education system, with the result that many of the young residents of Shanghai no longer speak the language fluently.

Because the younger generation of Shanghai residents has been educated in Mandarin Chinese, the Shanghainese they speak is often mixed with Mandarin words and expressions. This type of Shanghainese is quite different from the language that older generations speak, which has created fears that "real Shanghainese" is a dying language.

Modern Shanghainese

In recent years, a movement has started to try to preserve the Shanghai language by promoting its cultural roots. The Shanghai government is sponsoring educational programs, and there is a movement to reintroduce Shanghainese language learning from kindergarten through to university.

Interest in preserving Shanghainese is strong, and many young people, even though they speak a mixture of Mandarin and Shanghainese, see Shanghainese as a badge of distinction.

Shanghai, as one of the most important cities of the PRC, has important cultural and financial ties with the rest of the world. The city is using those ties to promote Shanghai culture and the Shanghainese language.
