Guangdong is rich in Guangzhou, Shenzhen, Dongguan and Foshan in the Pearl River Delta. It is very inaccurate to say that Guangdong is rich in speaking Guangfu dialect, which is what most people call Cantonese. Let&;s take a look at some data of GDP in Guangdong in 2017. Guangzhou, the capital city of Guangdong, really speaks Cantonese. The top six cities in Guangdong&;s GDP are Shenzhen, Guangzhou, Guangzhou, Foshan, Dongguan and Huizhou, all of which are cities in the Pearl River Delta, but only Guangzhou, Foshan and Dongguan are cities where people who mainly speak Cantonese live. Entrepreneurs in Shenzhen come from all over the country, and Mandarin is the most popular. Both the local residents of Shenzhen and Huizhou speak Hakka, which can be regarded as a city dominated by Hakka. The top 5 GDP per capita are Shenzhen, Guangzhou, Zhuhai, Foshan and Zhongshan. The per capita income exceeds 100,000 yuan every year. These five cities are really rich cities. Except for Shenzhen, the other four cities really speak vernacular. However, there are many places in Maoming, Zhanjiang, Jiangmen, Yangjiang, Zhaoqing and Yunfu that speak vernacular, but they are not very developed. They have a &”;relationship&”; with the provincial capital Guangzhou, which uses vernacular as the main language, but it is not necessarily developed. Therefore, it is definitely not accurate to say that Guangdong is rich in Guangfu District. Guangdong&;s development benefits from the Pearl River Delta&;s proximity to Hong Kong and Macao. It has long taken advantage of the opportunity of reform and opening up and the advantages of being close to this highly international metropolis with free trade and convenient business environment, complementing and combining advantages in people flow, logistics, resources, land, investment, information and other aspects, winning development opportunities and making these quite a few people rich first. Obviously, the development of these areas is not based on the advantage of convenient communication language with Guangzhou.
