Today I wanna teach you some Thai Northern language which is called " Kum-Muang" (กำเมือง). There are Chiang Mai, Mae-hong-sorn, Chaing Rai, Pa-yao, Nan, Lamphun, Lampang, Tark and Prae that use " Kam-Muang" for local conversation.
The gramma of Kam-Muang is similar to normal Thai language but using different vocabularies. Moreover, the Kam-Muang alpabets(Lanna alphabets or Tua Muang),are also different from Thai alphabets. For example,

However, I'm not the expert about Lanna alphabets or Tua Muang so if you want to learn more you can check out this website http://www.omniglot.com/writing/lanna.html or
