Cơm Âm Phủ is associated with many anecdotes, each carrying its own flavor, yet all explaining this unique name. One of the most frequently told stories is about King Minh Mang. Legend has it that during an incognito trip, the king lost his way and stopped at an old woman's house to ask for food.
Set in a thatched house with mud walls under the dim glow of an oil lamp, the old woman served a plate of white rice with simple prepared dishes such as chopped vegetables and meat. Although simple, the meal made a deep impression on the king. Later, upon returning to the palace, the king asked the royal chefs to recreate the dish, and because he had dined in a hazy setting like the "underworld" (âm phủ), the dish was named as such.
Another story relates that this rice dish originated in the early 19th century, established by an entrepreneur. The eatery usually opened late at night, catering to people returning late after watching traditional opera performances. The location was often secluded and remote, illuminated only by dim oil lamps. Therefore, diners playfully called it the "underworld" (âm phủ) rice shop, and gradually the name became attached to the dish.

In addition, Hue locals still pass down a witty verse:
“Want to eat a romantic plate of rice
There is the Hell eatery with ghosts lurking behind”.
Although there are various hypotheses, they all meet at a common point: this was once a dish for the common class and poor laborers, sold late at night in dimly lit spaces.
