Legends tell of a man named Diem Bat Phien who was adored for quietly helping the townspeople in need. It was said that he was a master in astrology, geography, exorcism, and could see what others couldn't, exposing injustices in conflicts. He was known as Dương Tiên Sinh. The Lam family invited Diem Bat Phien to help settle a dispute. As soon as he entered the house, he noticed a trail of "ghostly footprints" on the floor leading forward. Following the direction, Diem Bat Phien tackled and resolved the supernatural disturbances within the Lam household.
