CEI, abbreviated from the IATA airport code, refers to Mae Fah Luang – Chiang Rai
International Airport. Nowadays, the vast majority of
adolescents in Chiang Rai use the word "CEI" as a noun or perhaps an adjective, signifying that they are Chiangrai people. "CEI boy," additionally, can be referenced to a specific type of youth or even adult who,
originally from Chiang Rai, always surprises strangers with extremely cool things.
