It ran along the Pearl River from the 1st Quay (第一津) in the northwest to the outlet of the western moat (西濠) in the southeast.

This "creek" formed the eastern boundary of the Thirteen Factories and separated Xiguan from Nanguan, the old city's southern suburb and Chinese dockyards.

The foreign enclave on Shamian Island was usually excluded from Xiguan but Huangsha (黃沙; wong4 saa1; 'Yellow Sands') was usually included.

The northeastern area from the 1st Wharf to Taiping Gate was called Upper Xiguan (上西關; Shàng Xīguān; soeng6 sai1 gwaan1) and the southwestern area stretching to Huangsha was known as Lower Xiguan (下西關; Xià Xīguān; gaa6 sai1 gwaan1) In modern Guangzhou, the preservation district of Xiguan is formally defined as follows: The northern boundary of Xiguan is the #7 and #8 Zhongshan Roads (中山七路, Zhōngshān Qī Lù, and 中山八路, Zhōngshān Bā Lù) and its eastern boundary is Middle and South Renmin Roads (人民中路, Rénmín Zhōng Lù, and 人民南路, Rénmín Nán Lù).

On 27 October 2006, the Liwan District Government approved a preservation plan for Xiguan's traditional architecture and culture.

On the other hand, some people insist that arcades are structures built in 1925 when streets were extended and roads were constructed on a large scale in Guangzhou.

Arcades connect houses and make a long path for pedestrians to keep out wind, rain and the glare of sunshine.

Arcades seem to be exactly designed for the climate in Guangzhou and meanwhile makes it much more convenient for stores to display their goods and attract customers.
