1945年嘅香港、澳門、廣州及珠三角地圖，除部分地方嘅普及和傳統拼法外，大部分地名均使用粵音郵政式拼寫（例如順德是「Shuntak」，中山是「Chungshan」）。但如今這種符合廣府話發音規律嘅拼法只能在港澳及海外保留使用到今天。
In the 1945 map of Hong Kong, Macao, Guangzhou and the Pearl River Delta, most of the place names were spelled in Cantonese postal style (e.g. "Shuntak" for Shunde and "Chungshan" for Zhongshan) in addition to the popularity and traditional spelling of some places. But nowadays, this spelling that conforms to the pronunciation rules of Cantonese can only be retained and used in Hong Kong, Macao and overseas to this day.
