Do you know how many of the top 10 customs of the Spring Festival?

The Spring Festival, commonly known as “Nian Jie” or “Guo Nian”, is a grand and distinctive ancient festival in China’s folk culture, and it is also one of the liveliest traditional festivals. Narrowly speaking, the Spring Festival refers to the first day of the first lunar month, the first day of the new year. Broadly speaking, the Spring Festival lasts from the Laba Festival or the Little New Year all the way to the 19th day of the first lunar month of the following year, and all this period is considered the Spring Festival.

Here are 10 folk customs during the Spring Festival. Let’s see how many of them you know.

1. Spring Cleaning

According to the records in Lu’s Spring and Autumn Annals, as early as the era of Yao and Shun, there has been the custom of spring cleaning during the Spring Festival in China. Since the Chinese character for “dust” (“尘”) has the same pronunciation as the character for “old” (“陈”), spring cleaning has been given a new meaning. It means “getting rid of the old and ushering in the new”, hoping to sweep away all poverty and bad luck.

The Laba Festival

The Laba Festival, celebrated on the eighth day of the twelfth lunar month, is a traditional Chinese festival with rich and long-standing customs. These customs are deeply rooted in Chinese culture and have been passed down through generations. Here are some of the main traditions associated with the Laba Festival:

The Double Ninth Festival

The Double Ninth Festival, celebrated on the ninth day of the ninth lunar month, is a traditional Chinese festival with unique and meaningful customs. Rooted in ancient Chinese culture, this festival has been cherished for centuries. Here are some of the main customs associated with it:

1. Climbing Mountains (登高)
One of the most well-known customs of the Double Ninth Festival is climbing mountains. The ninth lunar month typically falls in autumn when the weather is clear and crisp, making it an ideal time for outdoor activities. People believe that climbing to high places on this day can help them avoid disasters and bad luck. It is also a great opportunity to enjoy the beautiful autumn scenery, breathe in the fresh air, and strengthen their bodies. Families and friends often go on mountain hikes together, chatting and enjoying each other’s company along the way.

2. Wearing Dogwood (插茱萸)
Wearing dogwood, known as “茱萸 (zhū yú)” in Chinese, is another traditional practice. Dogwood is a plant with a strong fragrance, and it was believed to have the power to ward off evil spirits, dispel diseases, and protect people from harm. People would pick fresh dogwood branches and wear them on their clothes, in their hair, or hang them on their doors. Although the belief in its protective powers may be more symbolic in modern times, the custom still remains as a connection to the festival’s long history.

3. Appreciating Chrysanthemums and Drinking Chrysanthemum Wine (赏菊和饮菊花酒)
Chrysanthemums are in full bloom during the autumn season, which coincides with the Double Ninth Festival. Appreciating chrysanthemums is a popular activity. People visit chrysanthemum exhibitions, where they can admire a wide variety of chrysanthemum species in different colors and shapes. Additionally, drinking chrysanthemum wine is also a traditional custom. Chrysanthemum wine is made by steeping chrysanthemum flowers in wine. It is said to have health benefits, such as improving eyesight and promoting longevity. Sipping chrysanthemum wine while enjoying the chrysanthemum displays is a way to savor the festival’s atmosphere.

4. Eating Chongyang Cakes (吃重阳糕)
Chongyang cakes, or “重阳糕 (chóng yáng gāo)”, are a traditional food for the Double Ninth Festival. These cakes are usually made from glutinous rice flour and can be filled with various ingredients like nuts, dried fruits, or sweet bean paste. The word “糕 (gāo)” in Chinese sounds the same as the word for “high”, so eating Chongyang cakes is a symbolic way of expressing the hope for continuous progress and upward mobility in life. They are also a delicious treat that families enjoy together during the festival.

5. Respecting and Caring for the Elderly (尊老敬老)
In modern times, the Double Ninth Festival has also become a day to show respect and care for the elderly. Given the pronunciation of the number “nine” in Chinese, which is associated with longevity, this festival is seen as an appropriate occasion to honor the elderly. Communities and families may organize activities such as visiting nursing homes, offering gifts and greetings to the elderly, and hosting gatherings to show their appreciation for the wisdom and experience that the elderly bring. This custom reflects the importance of filial piety and respect for the elderly in Chinese culture.

These customs of the Double Ninth Festival not only showcase the rich cultural heritage of China but also carry people’s good wishes for health, longevity, and a prosperous life.

The Mid-Autumn Festival

The Mid-Autumn Festival, celebrated on the 15th day of the 8th lunar month, is a significant traditional Chinese festival. It is a time for family reunions and various delightful customs that have been passed down through generations. Here are some of the main customs associated with this festival:

1. Admiring the Full Moon (赏月)
One of the most prominent customs of the Mid-Autumn Festival is admiring the full moon. On this night, the moon is believed to be the roundest and brightest of the year. Families and friends gather outdoors, often in gardens, parks, or on rooftops, to enjoy the beauty of the full moon. They sit together, chat, and soak in the serene and romantic atmosphere. This custom is deeply rooted in Chinese culture, symbolizing unity and completeness. Looking at the full moon, people often think of their distant relatives and friends, expressing their longing and love for them.

2. Eating Mooncakes (吃月饼)
Mooncakes are an essential part of the Mid-Autumn Festival. These round pastries are usually filled with a variety of ingredients such as lotus seed paste, red bean paste, salted egg yolks, or nuts. The round shape of mooncakes represents the full moon and symbolizes family reunion. People exchange mooncakes as gifts among family members, friends, and colleagues. Sharing mooncakes during the festival is not only a delicious treat but also a way to show care and strengthen relationships. There are also many regional variations in the flavors and styles of mooncakes, reflecting the diversity of Chinese cuisine.

3. Family Reunions (家庭团聚)
The Mid-Autumn Festival is a time when families make a special effort to come together. Family members who are away from home often travel back to be with their loved ones. They have a big dinner together, sharing stories, laughter, and the joy of being reunited. This sense of togetherness is highly valued in Chinese culture, and the festival provides an important opportunity for families to strengthen their bonds and create lasting memories.

4. Worshipping the Moon (祭月)
In some areas, there is a tradition of worshipping the moon. People set up an altar with mooncakes, fruits, and other offerings. They light incense and bow to the moon, expressing their gratitude and praying for good luck, health, and prosperity. This custom reflects the ancient Chinese people’s respect and awe for the moon, which was often associated with feminine virtues and the cycle of life.

5. Lantern Display and Lantern-related Activities (赏灯及与灯相关的活动)
Although not as prominent as during the Lantern Festival, there are also some lantern-related activities during the Mid-Autumn Festival, especially in some southern regions of China. People make and display various lanterns, which are often in the shapes of the moon, rabbits, or other symbols related to the festival. Children may carry small lanterns and play with them, adding a festive and lively atmosphere to the celebration. There may also be lantern riddle games, where people guess the answers to riddles written on the lanterns for fun and prizes.

6. Drinking Osmanthus Wine (饮桂花酒)
Osmanthus wine is a traditional beverage associated with the Mid-Autumn Festival. Made from osmanthus flowers, this wine has a sweet and fragrant taste. Drinking osmanthus wine is believed to bring good luck and symbolize a prosperous life. It is often shared among family members during the festival, enhancing the festive mood.

These customs of the Mid-Autumn Festival not only add charm and joy to the celebration but also play an important role in preserving and passing on Chinese cultural traditions from one generation to another.

The Zhongyuan Festival

The Zhongyuan Festival, also known as the Ghost Festival, is celebrated on the 15th day of the seventh lunar month in Chinese culture. It is a time when people pay respect to the spirits of the dead and perform various rituals to ensure their well-being in the afterlife. Here are some of the main customs associated with the Zhongyuan Festival:

1. Offering Sacrifices to Ancestors and Ghosts (祭祀祖先和亡灵)
One of the most important customs of the Zhongyuan Festival is making offerings to ancestors and the spirits of the deceased. Families prepare a variety of food items, such as fruits, vegetables, cooked meat, and rice, and place them on altars or at the gravesites. Incense is burned, and paper money, clothes, and other symbolic items made of paper are also offered. These offerings are believed to provide the spirits with the necessities they need in the afterlife. People bow and pray, expressing their respect and remembrance for their ancestors and hoping for their blessings.

2. Releasing River Lanterns (放河灯)
Releasing river lanterns is a widespread and symbolic custom during the Zhongyuan Festival. Lanterns are made from various materials like paper, bamboo, or wood, and are often decorated with colorful patterns. They are placed on rivers, lakes, or other bodies of water. The floating lanterns are thought to guide the lost souls of the dead back to the other world, helping them find their way. It is also believed that the light of the lanterns can dispel darkness and bring peace to the spirits. In some places, there are large-scale lantern-releasing events, with thousands of lanterns lighting up the water, creating a beautiful and solemn scene.

3. Holding Religious Ceremonies (举行宗教仪式)
Buddhists and Taoists hold special religious ceremonies on the Zhongyuan Festival. In Buddhist temples, monks conduct the “Ullambana” ceremony, which is based on the story of Maudgalyayana rescuing his mother from the underworld. They chant scriptures, offer food to the monks, and perform other rituals to relieve the suffering of the deceased. Taoist temples also hold rituals, with Taoist priests performing incantations and offering sacrifices to the gods and the spirits of the dead. These religious activities are aimed at helping the spirits achieve peace and liberation.

4. Avoiding Going Out at Night (夜晚避免外出)
Many people believe that on the night of the Zhongyuan Festival, the boundary between the living and the dead is blurred, and ghosts are more likely to roam the earth. To avoid any potential encounters with evil spirits or bad luck, some people choose to stay at home and avoid going out after dark. They believe that by staying indoors, they can protect themselves and their families from any harm that might be caused by the spirits. This custom reflects the traditional Chinese fear and respect for the supernatural world.

5. Burning Incense and Paper Offerings on the Streets (在街上焚香烧纸)
In addition to making offerings at home or at the gravesites, some people also burn incense and paper offerings on the streets during the Zhongyuan Festival. They create small altars on the roadside and place their offerings there. This is done to show respect and provide for the wandering spirits that may not have families to care for them. However, in modern times, due to environmental and safety concerns, many places have restrictions on such outdoor burning activities, and people are encouraged to find more environmentally friendly ways to perform these rituals.

These customs of the Zhongyuan Festival are deeply rooted in Chinese traditional culture and beliefs. They reflect people’s attitudes towards life and death, as well as their desire to maintain a connection with the spiritual world and ensure the well-being of both the living and the dead.

The Qixi Festival

The Qixi Festival, also known as the Double Seventh Festival or Chinese Valentine’s Day, falls on the seventh day of the seventh lunar month. It is a festival steeped in romantic legends and unique customs. Here are some of the main traditions associated with the Qixi Festival:

1. Needle Threading Competition (穿针乞巧)
One of the most prominent customs of the Qixi Festival is the needle threading competition, known as “乞巧 (qǐ qiǎo)” in Chinese, which means “praying for skills”. On this evening, young girls gather together and try to thread a needle with seven holes as quickly as possible. It is believed that the girl who can do it the fastest and most dexterously will be blessed with greater needlework skills and intelligence. This custom reflects the traditional emphasis on women’s handicraft skills in ancient China and their aspiration to become more skillful and capable.

2. Worshiping the Weaver Girl (拜织女)
In some areas, girls will set up a shrine to worship the Weaver Girl, one of the main characters in the Qixi legend. They will prepare fruits, flowers, and other offerings, and then kneel down and pray to the Weaver Girl. They may ask for her blessings in various aspects of their lives, such as improving their embroidery and sewing skills, finding a good husband, or having a happy and harmonious family. This act of worship shows people’s respect and yearning for the Weaver Girl’s wisdom and good fortune.

3. Making and Eating Qixi Cakes (制作和食用巧果)
Qixi cakes, also called “巧果 (qiǎo guǒ)”, are traditional pastries made for this festival. These cakes are often shaped like flowers, birds, or other delicate patterns. They are made from ingredients such as flour, sugar, and sesame seeds, and then deep-fried or baked. Eating these cakes is not only a delicious treat but also a way to celebrate the festival. The name “巧果” implies that by eating these cakes, people can gain some of the Weaver Girl’s ingenuity and dexterity.

4. Star Gazing (观星)
The Qixi Festival is closely related to the legend of the Cowherd and the Weaver Girl, who are separated by the Milky Way and can only meet once a year on this day. As a result, people often look up at the sky on the night of the Qixi Festival, hoping to see the Cowherd and the Weaver Girl stars. It is a romantic and symbolic activity, representing people’s yearning for true love and the hope that lovers can be together. Some people also make wishes while star gazing, believing that their wishes may come true under the witness of these stars.

5. Decorating with Pomegranates (用石榴装饰)
Pomegranates are often associated with the Qixi Festival. In some places, people will decorate their homes with pomegranates or pomegranate flowers. The pomegranate is a symbol of fertility, abundance, and good luck. Its many seeds are seen as a sign of a large and prosperous family. By using pomegranates for decoration, people express their hopes for a happy and fulfilling life, as well as their wish for a harmonious and prosperous family.

These customs of the Qixi Festival not only carry the beautiful legend of the Cowherd and the Weaver Girl but also reflect the Chinese people’s pursuit of love, wisdom, and a good life. They continue to be passed down and celebrated, adding a touch of romance and cultural charm to this special festival.

The Dragon Boat Festival

The Dragon Boat Festival, which falls on the fifth day of the fifth lunar month, is a significant traditional Chinese festival with a rich array of customs deeply rooted in history and culture. Here are some of the main traditions:

1. Dragon Boat Racing (赛龙舟)
Dragon boat racing is the most iconic activity of the Dragon Boat Festival. Teams of paddlers, often wearing matching outfits, row in unison to propel a long, narrow boat shaped like a dragon through the water. The boats are elaborately decorated with dragon heads and tails. Drummers on the boats beat out rhythms to coordinate the paddlers’ strokes, creating a thrilling and energetic atmosphere. This custom is believed to have originated from the local people’s efforts to search for Qu Yuan, an ancient patriotic poet, after he drowned himself in the Miluo River. The competitive and exciting nature of dragon boat racing has made it a popular sport not only in China but also in many other parts of the world.

2. Eating Zongzi (吃粽子)
Zongzi is a traditional food specifically associated with the Dragon Boat Festival. These are pyramid-shaped or triangular dumplings made of glutinous rice stuffed with various fillings, such as sweet red bean paste, salted duck eggs, or pieces of pork. The rice is wrapped in bamboo or reed leaves and then steamed or boiled. The origin of eating zongzi is also related to Qu Yuan. It is said that people threw zongzi into the river to prevent the fish from eating Qu Yuan’s body. Today, eating zongzi is a way to commemorate the poet and also a delicious treat during the festival. There are different regional variations in the ingredients and shapes of zongzi, reflecting the diversity of Chinese cuisine.

3. Hanging Mugwort and Calamus (挂艾草和菖蒲)
On the Dragon Boat Festival, people often hang mugwort and calamus on their doors and windows. These plants are believed to have the power to repel insects, ward off evil spirits, and bring good luck. Mugwort has a strong fragrance and is known for its medicinal properties, while calamus also has a pleasant smell and is thought to be effective in keeping pests away. Hanging these plants is a traditional way to protect the family from diseases and misfortunes during the season when the weather is getting warmer and insects are more active.

4. Wearing Sachets (佩戴香囊)
Sachets, also known as fragrant pouches, are small bags filled with a mixture of aromatic herbs, spices, and sometimes small pieces of jade or other decorative items. They are often sewn into beautiful and colorful patterns, such as animals or flowers. People, especially children, wear sachets around their necks or tie them to their clothes. The fragrant smell of the herbs inside is believed to keep away evil spirits and mosquitoes, and it is also thought to have a positive effect on health. Wearing sachets is not only a protective measure but also a form of traditional handicraft and a way to show personal style.

5. Drinking Realgar Wine (饮雄黄酒)
In some regions, it is a custom to drink realgar wine during the Dragon Boat Festival. Realgar is a mineral that has been used in traditional Chinese medicine. When dissolved in wine, it is believed to have the ability to dispel toxins, drive away evil spirits, and protect people from various diseases. However, due to the toxicity of realgar in large amounts, nowadays, people usually just smear a little realgar wine on the forehead or around the ears instead of drinking it directly. This custom is also associated with the legend of the White Snake, where the White Snake was made to reveal her true form after drinking realgar wine.

6. Wearing Five-colored Silk Thread (系五彩丝线)
Children are often given five-colored silk threads to wear on their wrists, ankles, or necks on the Dragon Boat Festival. The five colors, usually red, green, yellow, white, and black, are believed to represent the five elements in traditional Chinese philosophy (wood, fire, earth, metal, and water). Wearing these threads is thought to protect children from evil spirits and ensure their good health. The threads are usually worn from the Dragon Boat Festival until the seventh day of the seventh lunar month, when they are taken off and thrown into a river or burned, symbolizing the removal of bad luck.

These customs of the Dragon Boat Festival not only preserve the rich cultural heritage of China but also continue to be an important part of Chinese people’s lives, bringing people together and celebrating the festival with joy and tradition.
