卡尔梅克人
When not engaged in diplomacy between the Oirat and the Khalkha, Zaya Pandita spread Tibetan Buddhism to the Oirats, the Khalkha and even the Kalmyk people in far away Russia. In furtherance of his missionary work, Zaya Pandita composed a new alphabet, based on the traditional Mongolian alphabet, called "Clear script" ("todo bichig") to transcribe the Oirat language as it is pronounced. By doing so, Zaya Pandita eliminated the ambiguities of the traditional Mongolian alphabet.
