The SASM/GNC/SRC romanization of Tibetan, commonly known as Tibetan pinyin or ZWPY (Chinese: Zàngwén Pīnyīn 'Tibetan spelling'), is the official transcription system for the Lhasa dialect of the Tibetan language for personal names and place names in China. It is based on the pronunciation used by China National Radio's Tibetan Radio, which is based on the pronunciation of the Lhasa dialect, and reflects its pronunciation, except that it does not mark tone. It has been used within China as an alternative to the Wylie transliteration for writing Tibetan in the Latin script since 1982.Romanization of Tibetan Geographical Names – UNGEGN
