4. The Hungry Ghost Festival is about filial piety

 In an alternate version of the Buddhist origin of the Hungry Ghost Festival, it also holds deep significance as an act of filial piety. This narrative finds its roots in a Buddhist sutra, where a monk attains the status of an arhat and learns of his mother's rebirth as a hungry ghost, a consequence of her unkind actions during her human life.

 Determined to alleviate his mother's plight, the monk turns to the Buddha for guidance. Acting upon the Buddha's counsel, the monk initiates a practice of offering food and clothing to 500 bhikkhus (monks) annually on the 14th day of the seventh lunar month. Through the accumulation of his virtuous actions, his mother eventually regains human rebirth. This accounts for the reason why, during the Hungry Ghost Festival, Buddhists prayed to their ancestors as a way to show their filial piety.
