Why do few people in Chongqing and Chengdu speak Mandarin, and almost all of them are locals?

Unlike many cities in China, Chengdu and Chongqing are not typical immigrant cities. Most people who work and live in these two cities are Sichuan and Chongqing natives, and there is little difference between Sichuan and Chongqing dialects. Therefore, there is no obstacle to communication in dialects, and people are more cordial and fluent in Sichuan dialect.

2. There is another reason, which stems from the popularity of Putonghua, so that not everyone in Chongqing accepts Putonghua learning. At the same time, Mandarin is not standard and popular. If Mandarin is not up to standard, Chongqing people will speak less Mandarin, leading to such a cycle.

3. In their own cities, especially middle-aged and elderly people, the first reaction is the dialect of their hometown, so why do Chongqing people also speak dialects to foreigners? In addition, the Chongqing dialect of Southwest Mandarin is close to Mandarin, and Chongqing people think that everyone can understand Chongqing dialect, so they speak less Mandarin.
