Dongzhi is a special time that marks the winter solstice. This is the day with the shortest daylight and the longest night of the year. In the traditional Chinese calendar, it is the 22nd solar term. The name Dongzhi can mean "the coming of winter." It usually falls between December 21 and December 23. This festival is a way to celebrate the victory of light over darkness. People believe that after this day, the daylight hours will slowly grow longer. This brings a sense of balance and harmony to life.

Families celebrate this day by eating many different kinds of food together. In many communities, people make and eat tangyuan. These are round balls made of glutinous rice flour.

They can be pink or green and are served in sweet soup or savory broth. Tangyuan symbolize a family reunion. In China, some people also eat dumplings called shuijiao. A famous doctor named Zhang Zhongjing once shared lamb dumplings with the poor. He wanted to help them stay warm and prevent chilblains on their ears.

Because the dumplings look like ears, they are a special tradition.

The history of Dongzhi goes back a very long time. The Chinese people first celebrated it during the Zhou dynasty. This was between 1045 BCE and 256 BCE. Later, it became an official celebration during the Han dynasty. During the Han period, people would take breaks from work to be with family. They would worship heaven and honor their ancestors. They might burn joss paper at shrines to show gratitude. In ancient times, people called it the "festival of extreme length." This was because the sun's position makes shadows very long.

Different places have their own unique ways to observe this solar term. In Korea, the day is sometimes called "Small Seol." People there make a red bean porridge called patjuk. They also add round rice cakes called saealsim to the porridge. In Japan, the term is called Tōji. Some people in Japan drink hot grapefruit water or eat pumpkin. In Taiwan, people often eat "tonic" foods to stay healthy.

They might enjoy mutton hot pot or ginger duck hot pot to nourish their bodies during the cold months.

Dongzhi connects people to the natural world and the changing seasons. The solar term is divided into three parts called pentads. These are named after things happening in nature. One pentad is when earthworms form knots as they hibernate. Another is when deer shed their antlers. The last one is when spring water begins to move. These signs show that the earth is changing. Even today, many people feel a year older right after Dongzhi. It is a time to look forward to the returning light.

Dongzhi is a significant solar term in the traditional Chinese calendar. It marks the winter solstice, which is the day with the shortest daylight and the longest night of the year. In the solar calendar, this term begins when the Sun reaches a celestial longitude of 270 degrees. It ends when the Sun reaches 285 degrees. In the Gregorian calendar, this usually occurs between December 21 and December 23. The term "Dongzhi" carries deep meaning regarding the peak of the season. In Chinese, the character "Zhi" means "extreme," signifying the summit of winter. This makes the festival a celebration of the extreme point of the cold season.

The festival is rooted in the ancient philosophy of yin and yang. This system describes the balance and harmony of the cosmos through opposing forces. "Yang" represents positive energy, warmth, and light. During the winter solstice, the world experiences the height of "yin," or darkness and cold. However, the festival symbolizes the victory of light over darkness. After Dongzhi, the days gradually lengthen, meaning "Yang" energy begins to increase again. This transition is represented by the I Ching hexagram "fu," which means "Returning." It signifies the return of positive energy into the world.

Historically, the Dongzhi Festival has deep roots in Chinese civilization. It was first celebrated during the Zhou dynasty, which lasted from 1045 BCE to 256 BCE. Later, it became an official celebration during the Han dynasty from 206 BCE to 220 CE. In ancient times, people called it the "festival of extreme length." This name referred to how the Sun's extreme position caused shadows to lengthen. During the Han dynasty, people would take breaks from their work to celebrate. They performed ceremonies to worship heaven and honored their ancestors by burning joss paper at shrines. This was a major holiday, comparable in importance to the Chinese New Year.

Food plays a central role in how families celebrate Dongzhi. In many Asian communities, people make and eat tangyuan. These are round balls made from glutinous rice flour, sometimes colored pink or green. They are served in a sweet soup or a savory broth. Because of their round shape, tangyuan symbolize family reunion. In northern China, many people prefer to eat shuijiao, or dumplings. This custom is linked to the physician Zhang Zhongjing from the Han dynasty. He created a dumpling soup called "quhan jiaoer tang" to help the poor. These dumplings were filled with lamb and shaped like ears to prevent chilblains.

Different regions across Asia have developed their own unique traditions for this day. In Korea, the winter solstice is sometimes called "Small Seol." People there often prepare patjuk, which is a red bean porridge. They also add round rice cakes called saealsim to the dish. In the past, people even sprayed red bean porridge on doors to ward off bad ghosts. In Japan, the term is called Tōji. It is customary in some places to eat pumpkin or drink hot grapefruit water. In Taiwan, the festival is a time for making offerings to ancestors. They may offer nine-layer cakes shaped like animals such as ducks or pigs. These animals represent auspiciousness, or good luck, in Chinese tradition.

In Taiwan, the festival is also a time for eating "tonic" foods. These are nutritious foods meant to nourish the body and fight the cold. Because people's metabolic rates slow down in winter, they eat more fatty or meaty foods. This practice mimics how animals hibernate to preserve life and rejuvenate. Popular choices include mutton hot pot or ginger duck hot pot. People may also use herbs like ginseng or deer horn in their meals.

These foods are intended to strengthen the body's resistance during the "extreme of winter."

The solar term is also connected to the natural cycles of the earth. Each solar term is divided into three segments called pentads. These pentads are named after specific seasonal events in nature. The first pentad of Dongzhi is when earthworms form knots during hibernation. The second pentad is when deer shed their antlers. The third pentad is marked by the movement of spring water. These natural signs remind people of the constant changes in the environment. Even today, many people believe that they become a year older immediately after the Dongzhi celebration.
