Why the winter solstice is a celebration of light, reunion, and turning a year older
In short: Dongzhi, the winter solstice, marks the year's longest night and the return of light. Rooted in ancient yin and yang philosophy, this festival celebrates the shift toward longer days. Beyond the astronomy, it is a time for family reunions, ancestral worship, and eating symbolic foods to ensure health and prosperity.
The term Dongzhi, or 'arrival of winter,' signifies the summit of the season. Historically, the festival originated during the Zhou dynasty and became an official holiday under the Han. It is deeply connected to the I Ching hexagram fu, representing the 'returning' of light. As the sun reaches a celestial longitude of 270°, the longest night gives way to the gradual increase of yang—the positive energy associated with warmth and light.
Food plays a central role in these traditions, serving as both nourishment and symbolic protection. In many regions, families prepare tangyuan, glutinous rice balls that symbolize reunion. Another widespread custom involves eating dumplings, a tradition attributed to the physician Zhang Zhongjing. Legend holds that he created ear-shaped dumplings to protect the poor from frostbitten ears during a harsh winter. These dishes are often shared with friends and relatives as a blessing, with some families even using them as talismans to ward off evil spirits.
The festival is also a significant marker of personal growth. Many traditional observers consider themselves a year older immediately following Dongzhi, rather than waiting for the Lunar New Year. Beyond the home, the day historically involved agricultural rituals, such as harvesting winter crops and honoring livestock. In Taiwan, it is viewed as the ideal time for consuming tonic foods like mutton or ginger duck hot pot, mirroring the natural tendency of animals to preserve energy and rejuvenate during the colder months.
Cultural variations abound across East Asia. In Korea, the day is known as 'Small Seol,' where red bean porridge is traditionally used to ward off bad ghosts. In Japan, the term is Tōji, where customs include bathing in grapefruit-infused water and eating pumpkin. Whether through ancestral worship, settling debts, or gathering for a grand meal, Dongzhi remains a vital moment for balancing the cosmos and strengthening human connections.
