This daram is story of Thai Northern City (The Kingdom of Lanna). The culture of Thai Northern is a bit different from Thai Central. Most of city in northern of Thailand are the "Kingdom of Lanna" such as Chiangmai, Chiangrai, Lamphun etc. We have own language, culture, dresses in thai northern style (like the dresses and caractor in this drama).
I am now live in Chiangrai and speak Thai Northern lannguage.
