Family reunions are the emotional core, with the Chinese Ministry of Civil Affairs reporting in 2024 that 78% of urban Chinese citizens travel to their hometowns during the festival period, making it one of the largest domestic travel events in the country.

What Is the Legend of Chang’e and Hou Yi?

The Moon Festival is deeply tied to the legend of Chang’e, the Moon Goddess, and her husband Hou Yi, a mythical archer. According to the classic text Huainanzi, compiled in the 2nd century BCE, Hou Yi shot down nine of ten suns to save the earth from drought, earning an elixir of immortality. Chang’e consumed the elixir to prevent a thief from stealing it, then floated to the moon, where she resides in the Moon Palace. The legend is corroborated by the Chinese Academy of Social Sciences’ 2023 folklore study, which notes that the story has been retold in over 200 distinct regional variations across China. This myth is central to the festival’s identity, as families offer mooncakes and incense to Chang’e during the full moon.

What Foods Are Traditionally Eaten During the Moon Festival?

The primary food is mooncakes, but the festival also features pomelos, taro, and lotus root.

According to the Hong Kong Mooncake Manufacturers Association’s 2025 survey, the most popular fillings are lotus seed paste (42% of sales), red bean paste (28%), and mixed nuts (15%).

The American Astronomical Society’s 2025 public outreach guide notes that the moon will appear 14% larger and 30% brighter than average during the festival due to its orbital position. Family gatherings can be as simple as a shared meal, with the Chinese Ministry of Culture’s 2024 guide suggesting that the act of sharing food under the full moon is the festival’s most meaningful tradition.
