Hi, P'Nong...
I have a question want to ask u,
Have u ever do the letter for student who will collect data or make interview for thesis? If yes, would u make me a letter to identify me as Chulalongkorn student n currently doing research abt Korean tourist in Cambodia... for Ajan Nak to sign it cuz I already ask Ajan Buddhagarn but he commented me to ask u n Ajan Nak.
