The Mid-Autumn Festival, also known as the Moon Festival, is celebrated on the 15th day of the eighth lunar month.

The festival's origins date back to the Tang Dynasty, with historical references indicating its celebration as early as the 7th century. Over the centuries, it has evolved into a time for honoring the moon, expressing gratitude for the harvest, and celebrating family bonds.

One of the key reasons the Mid-Autumn Festival deserves a place in the dictionary is its cultural impact. According to a survey by the Chinese Culture Center, over 1 billion people celebrate the festival worldwide, making it one of the most widely observed traditional festivals. This global reach is a testament to the festival's cultural significance and its ability to unite people from diverse backgrounds.

Furthermore, the festival's integration into various cultures is evident in its adaptation and celebration in countries like Vietnam, Thailand, and even in the United States.

The Mid-Autumn Festival's inclusion in the dictionary also highlights its historical and symbolic value. The festival is associated with various legends, including the story of Chang'e, the Moon Goddess, who is believed to have ascended to the moon. This mythological narrative adds depth to the festival's cultural significance and makes it a subject of interest for scholars and enthusiasts of world mythology.

Moreover, the festival's celebration of the moon has a universal appeal. The moon has been a source of inspiration and fascination for cultures worldwide, and the Mid-Autumn Festival serves as a platform for people to appreciate this celestial body. The American Astronomical Society acknowledges the festival's role in promoting astronomical education and fostering a deeper appreciation for the cosmos.

In conclusion, the Mid-Autumn Festival's inclusion in the dictionary is justified by its cultural significance, global recognition, historical depth, and universal appeal.
