Shenzhen (also known as Pengcheng) is a sub-provincial city at the southern tip of Guangdong Province, People's Republic of China (PRC), and one of the cities under separate state planning in People's Republic of China (PRC). There is a "dapeng ancient city" in Dapeng Street in Shenzhen for more than 600 years, so it is called "Peng" for short. It is located in the coastal area of Guangdong Province, bordering Hong Kong New Territories in the south, Dongguan in the north, Daya Bay in the east, Huizhou in the west, the Pearl River Estuary in Zhuhai and Macau in the west. Immigrants from Shenzhen, especially from other provinces, far exceed the number of aborigines, so Mandarin has become the most common language, while Hakka and Cantonese are the main local languages. Weitou dialect and Dapeng dialect are also local languages.
