Nanjing dialect
Postal romanization, standardized in 1906, combined traditional spellings, local dialect, and "Nanking syllabary." Nanking syllabary is one of various romanization systems given in a popular Chinese-English dictionary by Herbert Giles. It is based on Nanjing pronunciation. The French administered the post office at this time. The system resembles traditional romanizations used in France. Many of these traditional spellings were created by French missionaries in the 17th and 18th centuries when Nanjing dialect was China's standard. Postal romanization was used only for place names.
