The Beihai Customs Building is the physical evidence of the loss of sovereignty of the Qing government of the District. The building was established in 1877 as the North Customs. It was the earliest customs established in Guangxi. The building was built in 1883. Although it was built by the Qing government, the key positions of the Zheng Deputy Tax Department and the Attorney General of the Customs were all held by foreigners. It is commonly known as "Beihaiguan", so the old site is a physical evidence of the loss of the old Chinese customs sovereignty. The customs building is located at the intersection of Beihai Old Street Scenic Area, which is very convenient for visiting and taking pictures.
