Why China’s postal system once used a unique, patchwork map of place names

In short: For nearly a century, China’s mail was sorted using a flexible, idiosyncratic system of romanization. Rather than forcing a single dialect on the entire country, postal authorities embraced local pronunciations and regional spellings, creating a linguistic map that defied standardization until the eventual rise of pinyin in the late 20th century.

In the late 19th century, as China’s postal services expanded, the need for a consistent way to write place names in Latin letters became urgent. The Imperial Maritime Customs Post, led by Robert Hart, initially relied on local postmasters to submit romanizations. However, these officials often defaulted to the Wade–Giles system, which was based on the Beijing dialect. By 1906, a conference in Shanghai formally adopted the Nanking syllabary. This system was not intended to establish a new national standard, but rather to serve as a compromise that could accommodate a wide variety of Mandarin pronunciations across different regions.

The resulting system, known as postal romanization, was famously eclectic. It preserved historical spellings like 'Peking' and 'Amoy' while using specific phonetic tweaks, such as the double 'o' in 'Soochow', to distinguish cities from others with similar names. This flexibility was a deliberate choice by the French-led postal administration, which sought to make the system accessible to non-English speakers. While critics often dismissed the resulting map as inconsistent, modern scholars argue that this idiosyncrasy was actually its greatest strength. By prioritizing local identity and provincial sound-equivalents, the post office created a system that reflected the true linguistic diversity of China.

The system faced several challenges, including a brief, rapid expansion between 1920 and 1921 when the post office experimented with the Soothill-Wade system. During this period, one-third of all postal establishments adopted these new spellings before the administration reverted to the Nanking syllabary. Postal romanization remained the dominant English-language form for Chinese cities until the People's Republic of China introduced pinyin in 1958. While the mainland government officially abolished the system in 1964, it persisted in Taiwan until 2002, leaving behind a complex legacy of how a nation names its geography.
