サパ
It was only when the French debarked in highland Tonkin in the late 1880s that Sa Pa, name of the Hmong hamlet, with "S" is pronounced almost as hard as "Ch" in French, "Sh" in English, "S" in standard Vietnamese, so Chapa as the French called it, began to appear on the national map. Near to the now Sa Pa townlet is "Sa Pả commune", which shows the origin in Hmong language of the location name.
