Is Cantonese spoken in Shenzhen?

The local language in Shenzhen is mainly Hakka, because Shenzhen used to be a security guard who spoke Hakka. Because Cantonese is the standard vernacular, many local people in Shenzhen also speak Cantonese. With the development of Shenzhen and becoming a special zone, more and more immigrants from various provinces have entered Shenzhen. Now, Mandarin has become the main language in Shenzhen.

The main reason why Hong Kong people speak Mandarin better than Guangzhou people is that their tone of voice is softer, and because they read Mandarin when they are young, unlike Guangzhou people who read Mandarin when they are studying, many concepts are expressed by learning Mandarin first and then hard translating it into Mandarin, so they lack many dialects and proverbs.
