In English translations of Chinese classical novels, a common pattern appears: a traveler sets out on a journey, and the narrator informs us that the destination is “fifty li” away. English readers pause, slightly confused. Is that far? Is it close? The word li floats in the text like a unit from another worldβbecause it is.
π Origin Story
Li (ι) is one of the oldest units of measurement in continuous use. It dates back to the Zhou Dynasty (1046β256 BCE), when it was standardized as roughly 405 meters. Over the centuries, its exact length fluctuated between dynasties and regions, creating a delightful chaos for modern historians. The Qin Dynasty standardized it at about 415 meters; the Tang Dynasty pushed it to 454 meters; the modern li is defined as exactly 500 meters, or half a kilometer.
The word entered English primarily through translations of Chinese literature. Western readers encountered it in the works of Pearl S. Buck, in translations of Journey to the West and Dream of the Red Chamber, and in early travelogues by missionaries and diplomats. Unlike yuan or kung fu, which entered English through daily contact, li arrived through books. It is a literary loanword.
Today, the li has been officially replaced by the metric system in China. Road signs display kilometers. Maps use meters. And yet, the word survives stubbornly in rural conversation, in classical idioms, and in the names of places: Nanjing’s Xinjiekou was once measured in li from the city gate; Beijing’s old city walls were spaced at intervals of li.
π Why It Matters
Li matters because it is a word that measures not just distance, but time. When a Chinese grandmother says the market is “two li away,” she is using a unit that her great-grandmother used, and her great-great-grandmother before that. The word connects modern Chinese speakers to a continuous history of measurement that predates the Roman Empire.
It also matters as a reminder of what is lost in translation. When an English reader encounters “fifty li” in a novel, they miss something: the rhythm of the number, the cultural weight of distance in a pre-industrial society, the poetic resonance that li carries in Chinese poetry. The word is untranslatable not because of its meaning, but because of its history.
