Chiangrai province is located in the northest of Thailand. Its name is meaning "Meng-Rai 's city" because it was established in the reign of King Meng-Rai in year 1262. In later Chiangrai, Chiangmai and Chiangsaen became colony of Myanmar in the reign of King Burengnong in 1558. Until year 1804, two cites (Chiangmai and Chiangrai) were retrieved and returned to Siam or Thailand in the reign of Rama I in early Ratanakosin but Chiangsaen city was leaved to be deserted. King Rama III recovered Chiangrai city in order to be town of Chiangmai for protecting Myanmar 's invasion.
