Why don't Chengdu people speak Mandarin like Shenzhen people?

It shows that there are not many migrants in Chengdu. Shenzhen has a huge foreign population. Everyone comes from all corners of the country. Naturally, everyone speaks Mandarin. Otherwise, everyone speaks their own hometown dialect. Who can understand?

This also shows the rapid development of Shenzhen. Talents from all over the country come to Shenzhen for development, and it is not good to prevent Shenzhen from leading the whole country.

Putonghua is a modern standard Chinese with Beijing pronunciation as the standard pronunciation, northern dialect (Mandarin) as the basic dialect, and typical modern vernacular writings as the grammatical norm. As one of the working languages of the United Nations, Putonghua has become an important bridge for cultural exchanges between China and foreign countries and the first choice for foreigners to learn Chinese. By 215, 7% of the population in China has the ability to use Putonghua, and about 4 million people are still limited to one-way communication. The "Implementation Plan of the National Common Language Popularization Project" plans to "basically popularize the national common language throughout the country by 22", specifically, the national Putonghua popularization rate will reach more than 8% on average.

The word "Mandarin" appeared in the late Qing Dynasty. In 199, the Qing court designated Beijing Mandarin as "Mandarin". During the Republic of China, the pronunciation of Mandarin was formulated many times. After the founding of New China, Mandarin was designated as the national common language in 1955. The predecessor of Mandarin is Mandarin in Ming and Qing Dynasties, and it was called Yayan before that.
