Monday was the Mid-Autumn Festival celebrated notably by the Chinese and Vietnamese people.
The Chinese have celebrated the harvest during the autumn full moon since the Shang dynasty (c. 1600–1046 BCE). Morris Berkowitz, who studied the Hakka people during the 1960s, theorizes that the harvest celebration originally began with worshiping mountain deities after the harvest was completed. For the Baiyue peoples, the harvest time commemorated the dragon who brought rain for the crops. The celebration as a festival only started to gain popularity during the early Tang dynasty (618–907 CE).One legend explains that Emperor Xuanzong of Tang started to hold formal celebrations in his palace after having explored the Moon-Palace. The term mid-autumn (中秋) first appeared in Rites of Zhou, a written collection of rituals of the Western Zhou dynasty (1046–771 BCE).
Of course there are certain types of food involved.
Mooncakes: Making and sharing mooncakes is one of the hallmark traditions of this festival. In Chinese culture, a round shape symbolizes completeness and reunion. Thus, the sharing and eating of round mooncakes among family members during the week of the festival signifies the completeness and unity of families.
Imperial dishes: served on this occasion included nine-jointed lotus roots which symbolize peace, and watermelons cut in the shape of lotus petals which symbolize reunion.
Teacups & Wine: Teacups were placed on stone tables in the garden, where the family would pour tea and chat, waiting for the moment when the full moon's reflection appeared in the center of their cups.Owing to the timing of the plant's blossoms, cassia wine is the traditional choice for the "reunion wine" drunk on the occasion. Also, people will celebrate by eating cassia cakes and candy.
Food offerings: made to deities are placed on an altar set up in the courtyard, including apples, pears, peaches, grapes, pomegranates, melons, oranges, and pomelos.One of the first decorations purchased for the celebration table is a clay statue of the Jade Rabbit.
Nowadays, in southern China, people will also eat some seasonal fruit that may differ in different district but carrying the same meaning of blessing.
The festival celebrates three fundamental concepts that are closely connected:
Gathering, such as family and friends coming together, or harvesting crops for the festival. It's said the moon is the brightest and roundest on this day which means family reunion. And this is the main reason why people think mid-autumn is important.
Thanksgiving, to give thanks for the harvest, or for harmonious unions
Praying (asking for conceptual or material satisfaction), such as for babies, a spouse, beauty, longevity, or for a good future
Traditions and myths surrounding the festival are formed around these concepts, although traditions have changed over time due to changes in technology, science, economy, culture, and religion.
