Please answer the following question: Generate a question about the following movie plot: Khan, a Nong Khai native now attending university in Bangkok comes home for the annual Naga fireballs festival, just as a debate is raging over the cause of the fireballs. A local physician, Dr. Nortai, believes there is a scientific explanation for the phenomenon. A university professor, Dr. Suraphol, thinks the fireballs are manmade and are a hoax. Khan knows the truth: Having grown up as a dek wat at a Buddhist temple across the river in Laos, he helped the temple's abbot and the monks there to create fireballs and plant them on the bed on the Mekong. It is how he grew up to become such a strong swimmer and obtain an athletic scholarship. The temple's abbot, Luang Poh Loh, seeks Khan out and begs him to once again help with the planting of the fireballs. But Khan, weary of perpetuating a myth and of the crowds that accompany it, refuses. This sets up a conflict between science and religion that threatens to change the annual celebration. For his part, Luang Poh Loh is philosophical, advising "Do what you believe, believe in what you do."
Answer:
Who is the temple's abbot?
