Zhongying Street is located in Sha Tau Kok, which was the former site of Xin 'an County. It is backed by Wu Tong and faces Dapeng Bay in the south. This is a hot land with a long history, beauty, richness and vitality. It combines ancient civilization and modern culture, and has a unique natural and humanistic environment for developing tourism economy and culture. Zhongying Street was originally a muddy river called Cormorant Path. Due to the economic development, it has gradually evolved into a bustling border trade street, enjoying the reputation of a shopping paradise. Although it is only 250 meters long and 3-4 meters wide, its historical changes are the epitome of China's modern history. The boundary pillar erected on Zhongying Street is not only a historical witness of China's poverty and backwardness, the decline of the Qing Dynasty and the crazy invasion of British imperialism, but also a historical witness of reform and opening up, the return of Hong Kong to the motherland and the prosperity of China. The special historical background and cultural landscape of "Zhongying Street, One Street, Two Systems" is unique not only in China, but also in the world.
