The Mid-Autumn Festival (中秋節) is a harvest festival celebrated notably by the Chinese and Vietnamese^[2][3] people. It relates to Chuseok (in Korea) and Tsukimi (in Japan). The festival is held on the 15th day of the 8th month of the lunar calendar with a full moon at night, corresponding to mid September to early October of the Gregorian calendar.^[2]

Mooncakes, a rich pastry typically filled with sweet-bean or lotus-seed paste, are traditionally eaten during the festival.^{[4][5][6][7][8]}

The Mid-Autumn Festival is also known by other names, such as:

The festival celebrates three fundamental concepts that are closely connected:

Traditions and myths surrounding the festival are formed around these concepts,^[11] although traditions have changed over time due to changes in technology, science, economy, culture, and religion.^[11] It's about well being together.

The Chinese have celebrated the harvest during the autumn full moon since the Shang dynasty (c. 1600–1046 BCE).^[11][12] For the Baiyue peoples, the harvest time commemorated the dragon who brought rain for the crops.^[3] The celebration as a festival only started to gain popularity during the early Tang dynasty (618–907 CE).^[2] One legend explains that Emperor Xuanzong of Tang started to hold formal celebrations in his palace after having explored the Moon-Palace.^[11] 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).^[2] As for the royal court, it is dedicated to the goddess Taiyinxingjun(太陰星君 Tàiyīn xīng jūn );.And current still in taoism and Chinese folk religion^[13][14][14]

Empress Dowager Cixi (late 19th century) enjoyed celebrating Mid-Autumn Festival so much that she would spend the period between the thirteenth and seventeenth day of the eighth month staging elaborate rituals.^[15]

An important part of the festival celebration is moon worship. The ancient Chinese believed in rejuvenation being associated with the moon and water, and connected this concept to the menstruation of women, calling it "monthly water".^[9] The Zhuang people, for example, have an ancient fable saying the sun and moon are a couple and the stars are their children, and when the moon is pregnant, it becomes round, and then becomes crescent after giving birth to a child. These beliefs made it popular among women to worship and give offerings to the moon on this evening.^[9] In some areas of China, there are still customs in which "men do not worship the moon and the women do not offer sacrifices to the kitchen gods."^[9]

Offerings are also made to a more well-known lunar deity, Chang'e, known as the Moon Goddess of Immortality. The myths associated with Chang'e explain the origin of moon worship during this day. One version of the story is as follows, as described in Lihui Yang's Handbook of Chinese Mythology:^[16]

Handbook of Chinese Mythology also describes an alternate common version of the myth:^[16]

The festival was a time to enjoy the successful reaping of rice and wheat with food offerings made in honor of the moon. Today, it is still an occasion for outdoor reunions among friends and relatives to eat mooncakes and watch the moon, a symbol of harmony and unity. During a year of a solar eclipse, it is typical for governmental offices, banks, and schools to close extra days in order to enjoy the extended celestial celebration an eclipse brings.^[17] The festival is celebrated with many cultural or regional customs, among them:

A notable part of celebrating the holiday is the carrying of brightly lit lanterns, lighting lanterns on towers, or floating sky lanterns.^[2] Another tradition involving lanterns is to write riddles on them and have other people try to guess the answers (simplified Chinese: 灯谜; traditional Chinese: 燈謎; pinyin: dēng mí; literally: 'lantern riddle').^[18]

It is difficult to discern the original purpose of lanterns in connection to the festival, but it is certain that lanterns were not used in conjunction with moon-worship prior to the Tang dynasty.^[11] Traditionally, the lantern has been used to symbolize fertility, and functioned mainly as a toy and decoration. But today the lantern has come to symbolize the festival itself.^[11] In the old days, lanterns were made in the image of natural things, myths, and local cultures.^[11] Over time, a greater variety of lanterns could be found as local cultures became influenced by their neighbors.^[11]

As China gradually evolved from an agrarian society to a mixed agrarian-commercial one, traditions from other festivals began to be transmitted into the Mid-Autumn Festival, such as the putting of lanterns on rivers to guide the spirits of the drowned as practiced during the Ghost Festival, which is observed a month before.^[11] Hong Kong fishermen during the Qing dynasty, for example, would put up lanterns on their boats for the Ghost Festival and keep the lanterns up until Mid-Autumn Festival.^[11]

In Vietnam, children participate in parades in the dark under the full moon with lanterns of various forms, shapes, and colors. Traditionally, lanterns signified the wish for the sun's light and warmth to return after winter.^[19] In addition to carrying lanterns, the children also don masks. Elaborate masks were made of papier-mâché, though it is more common to find masks made of plastic nowadays.^[3] Handcrafted shadow lanterns were an important part of Mid-Autumn displays since the 12th-century Lý dynasty, often of historical figures from Vietnamese history.^[3] Handcrafted lantern-making declined in modern times due to the availability of mass-produced plastic lanterns, which often depict internationally recognized characters such as Pokémon's Pikachu, Disney characters, SpongeBob SquarePants, and Hello Kitty.^[3]

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.^[20] In some areas of China, there is a tradition of making mooncakes during the night of the Mid-Autumn Festival.^[21] The senior person in that household would cut the mooncakes into pieces and distribute them to each family member, signifying family reunion.^[21] In modern times, however, making mooncakes at home has given way to the more popular custom of giving mooncakes to family members, although the meaning of maintaining familial unity remains.

Although typical mooncakes can be around a few centimetres in diameter, imperial chefs have made some as large as 8 meters in diameter, with its surface pressed with designs of Chang'e, cassia trees, or the Moon-Palace.^[17] One tradition is to pile 13 mooncakes on top of each other to mimic a pagoda, the number 13 being chosen to represent the 13 months in a full lunar year.^[17] The spectacle of making very large mooncakes continues in modern China.^[22]

According to Chinese folklore, a Turpan businessman offered cakes to Emperor Taizong of Tang in his victory against the Xiongnu on the fifteenth day of the eighth lunar month. Taizong took the round cakes and pointed to the moon with a smile, saying, "I'd like to invite the toad to enjoy the hú (胡) cake." After sharing the cakes with his ministers, the custom of eating these hú cakes spread throughout the country.^[23] Eventually these became known as mooncakes. Although the legend explains the beginnings of mooncake-giving, its popularity and ties to the festival began during the Song dynasty (906–1279 CE).^[11]

Another popular legend concerns the Han Chinese's uprising against the ruling Mongols at the end of the Yuan dynasty (1280–1368 CE), in which the Han Chinese used traditional mooncakes to conceal the message that they were to rebel on Mid-Autumn Day.^[18] Because of strict controls upon Han Chinese families imposed by the Mongols in which only 1 out of every 10 households was allowed to own a knife guarded by a Mongolian guard, this coordinated message was important to gather as many available weapons as possible.

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.^[17] 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.^[17] 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.^[24][25][26]

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.^[27] One of the first decorations purchased for the celebration table is a clay statue of the Jade Rabbit. In Chinese folklore, the Jade Rabbit was an animal that lived on the moon and accompanied Chang'e. Offerings of soy beans and cockscomb flowers were made to the Jade Rabbit.^[17]

Nowadays, in southern China, people will also eat some seasonal fruit that may differ in different district but carrying the same meaning of blessing.

In Vietnam, cakes and fruits are not only consumed, but elaborately prepared as food displays. For example, glutinous rice flour and rice paste are molded into familiar animals. Pomelo sections can be fashioned into unicorns, rabbits, or dogs.^[3] Villagers of Xuân La, just north of Hanoi, produce tò he, figurines made from rice paste and colored with natural food dyes.^[3] Into the early decades of the twentieth century of Vietnam, daughters of wealthy families would prepare elaborate centerpieces filled with treats for their younger siblings. Well-dressed visitors could visit to observe the daughter's handiwork as an indication of her capabilities as a wife in the future. Eventually the practice of arranging centerpieces became a tradition not just limited to wealthy families.^[3]

The Mid-Autumn moon has traditionally been a choice occasion to celebrate marriages. Girls would pray to moon deity Chang'e to help fulfill their romantic wishes.^[15]

In some parts of China, dances are held for young men and women to find partners. For example, young women are encouraged to throw their handkerchiefs to the crowd, and the young man who catches and returns the handkerchief has a chance at romance.^[2] In Daguang, in southwest Guizhou Province, young men and women of the Dong people would make an appointment at a certain place. The young women would arrive early to overhear remarks made about them by the young men. The young men would praise their lovers in front of their fellows, in which finally the listening women would walk out of the thicket. Pairs of lovers would go off to a quiet place to open their hearts to each other.^[9]

Into the early decades of the twentieth century Vietnam, young men and women used the festival as a chance to meet future life companions. Groups would assemble in a courtyard and exchange verses of song while gazing at the moon. Those who performed poorly were sidelined until one young man and one young woman remained, after which they would win prizes as well as entertain matrimonial prospects.^[3]

During the 1920s and 1930s, ethnographer Chao Wei-pang conducted research on traditional games among men, women and children on or around the Mid-Autumn day in the Guangdong Province. These games relate to flights of the soul, spirit possession, or fortunetelling.^[17]

A unique tradition is celebrated quite exclusively in the island city of Xiamen. On the festival, families and friends gather to play a gambling sort of game involving 6 dice. People take turns in rolling the dice in a ceramic bowl with the results determining what they win. The number 4 is mainly what determines how big the prize is.^[28]

In Hong Kong and Macau, the day after the Mid-Autumn Festival is a public holiday rather than the festival date itself (unless that date falls on a Sunday, then Monday is also a holiday), because many celebration events are held at night. There are a number of festive activities such as lighting lanterns, but mooncakes are the most important feature there. However, people don't usually buy mooncakes for themselves, but to give their relatives as presents. People start to exchange these presents well in advance of the festival. Hence, mooncakes are sold in elegant boxes for presentation purpose. Also, the price for these boxes are not considered cheap—a four-mooncake box of the lotus seeds paste with egg yolks variety, can generally cost US$40 or more.^[29] However, as environmental protection has become a concern of the public in recent years, many mooncake manufacturers in Hong Kong have adopted practices to reduce packaging materials to practical limits.^[30] The mooncake manufacturers also explore in the creation of new types of mooncakes, such as ice-cream mooncake and snow skin mooncake.

There are also other traditions related to the Mid-Autumn Festival in Hong Kong. Neighbourhoods across Hong Kong set impressive lantern exhibitions with traditional stage shows, game stalls, palm readings, and many other festive activities. The grandest celebrations take place in Victoria Park (Hong Kong).^[31] One of the brightest rituals is the Fire Dragon Dance dating back to the 19th century and recognised as a part of China's intangible cultural heritage.^[32][33] The 200 foot-long fire dragon requires more than 300 people to operate, taking turns. The leader of the fire dragon dance would pray for peace, good fortune through blessings in Hakka. After the ritual ceremony, fire-dragon was thrown into the sea with lanterns and paper cards, which means the dragon would return to sea and take the misfortunes away.^[33]

Before 1941, There were also some celebration of Mid-Autumn Festival held in small villages in Hong Kong. Sha Po would celebrate Mid Autumn Festival in every 15th day of the 8th lunar month.^[34] People called Mid Autumn Festival as Kwong Sin Festival, they hold Pok San Ngau Tsai at Datong Pond in Sha Po. Pok San Ngau Tsai was a celebration event of Kwong Sin Festival, people would gather around to watch it. During the event, someone would play the percussions, Some villagers would then acted as possessed and called themselves as "Maoshan Masters". They burnt themselves with incense sticks and fought with real blades and spears.

The Mid-Autumn festival is named "Tết Trung Thu" in Vietnamese. It is also known as Children's Festival because of the event's emphasis on children.^[10] In olden times, the Vietnamese believed that children, being innocent and pure, had the closest connection to the sacred and natural world. Being close to children was seen as a way to connect with animist spirits and deities.^[19]

In its most ancient form, the evening commemorated the dragon who brought rain for the crops.^[3] Celebrants would observe the moon to divine the future of the people and harvests. Eventually the celebration came to symbolize a reverence for fertility, with prayers given for bountiful harvests, increase in livestock, and human babies. Over time, the prayers for children evolved into a celebration of children.^[3] Confucian scholars continued the tradition of gazing at the moon, but to sip wine and improvise poetry and song.^[3] By the early twentieth century in Hanoi, the festival had begun to assume its identity as a children's festival.^[3]

Aside from the story of Chang'e (Vietnamese: Hằng Nga), there are two other popular folktales associated with the festival. The first describes the legend of Cuội, whose wife accidentally urinated on a sacred banyan tree. The tree began to float towards the moon, and Cuội, trying to pull it back down to earth, floated to the moon with it, leaving him stranded there. Every year, during the Mid-Autumn Festival, children light lanterns and participate in a procession to show Cuội the way back to Earth.^[35] The other tale involves a carp who wanted to become a dragon, and as a result, worked hard throughout the year until he was able to transform himself into a dragon.^[10]

One important event before and during the festival are lion dances. Dances are performed by both non-professional children's groups and trained professional groups. Lion dance groups perform on the streets, going to houses asking for permission to perform for them. If the host consents, the "lion" will come in and start dancing as a blessing of luck and fortune for the home. In return, the host gives lucky money to show their gratitude.

In the Philippines, the Chinese Filipino community celebrate the evening and exchange mooncakes with fellow friends, families and neighbors.^[12] A game of chance, originating from the island city of Xiamen in China,^[28] known as Pua Tiong Chiu which means "mid-autumn gambling" in Philippine Hokkien (see 中秋博饼), or simply mid-autumn dice game, is also played by both Filipino-Chinese and Filipinos alike.^[36]

In Taiwan, the Mid-Autumn Festival is a public holiday. Outdoor barbecues have become a popular affair for friends and family to gather and enjoy each other's company.^[37] As of 2016, Taipei City designated 15 riverside parks to accommodate outdoor barbecues for the public.^[38]

Similar traditions are found in other parts of Asia and also revolve around the full moon. These festivals tend to occur on the same day or around the Mid-Autumn Festival.

The Japanese moon viewing festival, o-tsukimi, is also held at this time. People picnic and drink sake under the full moon to celebrate the harvest.

Chuseok (추석; 秋夕; [tɕʰu.sʌk̚]), literally "Autumn eve", once known as hangawi (한가위; [han.ɡa.ɥi]; from archaic Korean for "the great middle (of autumn)"), is a major harvest festival and a three-day holiday in North Korea and South Korea celebrated on the 15th day of the 8th month of the lunar calendar on the full moon. It was celebrated as far back as during the Three Kindoms period in Silla. As a celebration of the good harvest, Koreans visit their ancestral hometowns, honor their ancestors in a family ceremony (제사), and share a feast of Korean traditional food such as songpyeon (송편), tohrangook (토란국), and rice wines such as sindoju and dongdongju.

Many festivals revolving around a full moon are also celebrated in Cambodia, Laos, Myanmar and Sri Lanka. Like the Mid-Autumn Festival, these festivals have Buddhist origins and revolve around the full moon however unlike their East Asian counterparts they occur several times a year to correspond with each full moon as opposed to one day each year. The festivals that occur in the lunar months of Ashvini and Kṛttikā generally occur during the Mid-Autumn Festival.^[39][40]

In Cambodia, it is more commonly called "Full Moon Festival" by locals (as Cambodia does not have an Autumn season). Cambodians organize “the traditional festival of prostrating the moon". In that early morning, people start preparing sacrifices to worship the moon, including fresh flowers, cassava soup, flat rice, and sugar cane juice. At night, people put the sacrifices into a tray, place on a big mat, and sit at ease waiting for the moon. When the moon rises up over the top of a branch, everyone whole-heartedly worships the moon, implores blessings. After the ritual of worshipping the moon, the old take flat rice to put into the mouth of children until they are entirely full in order to spray for perfection, and good things. Many Cambodians celebrate this festival as it is believed that exchanging moon cake during this time is thought to bring luck and prosperity. Among Cambodians, this holiday is associated with Khmer beliefs of 'Sampeah Preah Ke' translated to "Praying to the Moon" and the Buddhist legend of the rabbit.^[41][42]

In Laos, many festivals are held on the day of the full moon. The most popular festival known as the That Luang Festival is associated with Buddhist legend and is held at Pha That Luang temple in Vientiane. The festival often lasts for three to seven days. A procession occurs and many people visit the temple.^[43]

In Myanmar, numerous festivals are held on the day of the full moon however Thadingyut Festival is the most popular one and occurs in the month of Thadingyut. It also occurs around the time of the Mid-Autumn Festival, depending on the lunar calendar. It is one of the biggest festivals in Myanmar after the New Year festival, Thingyan. It is a Buddhist festival and many people go to the temple to pay respect to the monks and offer food.^[44] It is also a time for thanksgiving and paying homage to Buddhist monks, teachers, parents and elders.^[45]

In Sri Lanka, a full moon day is known as Poya and each full moon day is a public holiday. Shops and businesses are closed on these days as people prepare for the full moon.^[46] Exteriors of buildings are adorned with lanterns and people often make food and go to the temple to listen to sermons.^[47] The Binara Full Moon Poya Day and Vap Full Moon Poya Day occur around the time of the Mid-Autumn Festival and like other Buddhist Asian countries, the festivals celebrate the ascendance and culmination of the Buddha's visit to heaven and for the latter, the acknowledgement of the cultivation season known as "Maha".^[48][49][50]
