Because Linjiang Province is fictional, and the police street in Guangdong Province is exactly the same as Linjiang Province, it is judged that Guangdong Province is the prototype of Linjiang Province. Guangdong Province, referred to as "Guangdong" for short, is the provincial administrative region of People's Republic of China (PRC). Because the East generally believes in ancient place names, it was named "Guangdong". Located in the south of Nanling and on the coast of the South China Sea, it borders Hong Kong, Macao, Guangxi, Hunan, Jiangxi and Fujian, and faces Hainan across the sea.

Guangdong Province is the southern gate of China and the shipping hub of the South China Sea. In the Han Dynasty, Xuwen ancient port was the origin port of the Maritime Silk Road, which officially opened the first page of the history of maritime exchanges between China and the West. In Qing Dynasty, Guangzhou became the only foreign trade port in China. After the reform and opening up, Guangdong has become the frontier of reform and opening up and the window to introduce western economy, culture and technology.
