The painting "Long van khe hoi" (Nine dragons in the clouds) is a masterpiece on the ceiling of the old main hall of Dieu De Pagoda, which has been moved around 20 meters backward, and is currently being well preserved to the surprise of many. The painting used to be a topic of heated debate for many years regarding whether to keep in the old main hall or to dismantle it. Dismantling it also meant erasing this masterpiece.
