Status

Relationship with downtown accents (especially Dongshan accents) 
Xiguan lies to the west of Taiping Gate (). Xiguan is the suburb of Guangzhou and it was administrated by Nanhai County rather than Panyu County (covering former Yuexiu District and former Dongshan District). Therefore, it was not regarded as part of the capital of Guangdong Province. Therefore, Xiguan Dialect should be regarded as suburban accents, distinguished from Downtown Accent (), esp. Dongshan Accents (). Notwithstanding, Xiguan lies close to the provincial capital, so the gap is narrow.
