Autumn Equinox (秋分) Food Therapy: Seasonal Menu & TCM Guide

Solar Term Origin (节气由来)

Qiufen (秋分), meaning "Autumn Equinox," is the 16th solar term and typically falls on September 22, 23, or 24. The word "fen" (分) means "to divide" or "to split equally." On this day, day and night are of equal length across the globe — the sun is directly above the equator, and the hours of light and darkness are perfectly balanced. In ancient China, this equilibrium was deeply significant. Qiufen represents the midpoint of autumn, dividing the season into two equal halves. After this day, the nights grow longer than the days, and yang energy begins its natural retreat as yin energy ascends.

Agriculturally, Qiufen is a time of abundance and harvest. Across China, autumn crops are gathered — rice, corn, soybeans, and cotton. The National Harvest Festival (中国农民丰收节) is celebrated on Qiufen, honoring the agricultural bounty of the season. The ancient phenological signs for Qiufen are: "thunder begins to subside; hibernating insects seal their burrows; water begins to dry up." The silencing of thunder marks the retreat of yang energy; insects closing their holes represents nature's turn inward; and the diminishing of surface water signals the increasing dryness of late autumn. These observations reflect a world in contraction, gathering its energy for the cold months ahead.

The most famous Qiufen folk tradition is "eating crab at autumn equinox" (秋分吃蟹). By Qiufen, crabs — especially the prized hairy crab (大闸蟹) from the Yangtze River Delta — have reached their peak: the roe is rich and golden, the meat is sweet and firm. The Chinese saying goes: "Autumn wind rises, crab legs itch" — meaning the season for crabs has arrived. In TCM, crab is cold in nature, so it is traditionally paired with ginger and vinegar to balance its cooling effect. Other Qiufen customs include eating autumn vegetables (qiu cai 秋菜), a wild amaranth that is believed to support overall health, and the practice of "standing eggs upright" (竖蛋), a game symbolizing balance and harmony. In some regions, people extend their longevity by eating "tang yuan" (glutinous rice balls) — a custom reflecting the wish for wholeness and long life.

Seasonal Food Therapy Principle (季节食补)

Qiufen is the pivot point of autumn. Before Qiufen, the dominant concern was heat-type dryness (温燥); after Qiufen, the dryness shifts to cool-type (凉燥), and the cold of winter begins to approach. In TCM theory, this is the moment when yin and yang are in perfect balance — day equals night, and the body should mirror this equilibrium. The Lung (肺) remains the organ of focus, as it governs the autumn season and the Metal element. However, at Qiufen, the emphasis expands: it is not enough to simply moisten the lungs; one must also nourish yin, support the spleen and stomach, and prepare the body for the transition toward cold.

The core TCM food therapy principle for Qiufen is to nourish yin, moisten the lungs, and achieve balance (养阴润肺调和). The word "balance" is key: the diet should be neither too cooling (which would damage the spleen as cold approaches) nor too warming (which would aggravate dryness). Neutral and slightly moistening foods are preferred — chestnut, Chinese yam, lily bulb, lotus root, white fungus, and autumn pear. Chestnut, in particular, is the signature food of Qiufen: it is warm and sweet, entering the Spleen, Stomach, and Kidney channels, and is traditionally used to strengthen the spleen, nourish the kidneys, and build energy reserves for winter. The tradition of eating crab at this time is balanced by the use of warming ginger and vinegar — a perfect example of TCM's emphasis on harmony and counterbalance. The diet should also support the spleen and stomach, as these organs will need to be strong to process the richer, more nourishing foods of late autumn and winter. Moderate, balanced eating is the guiding principle: neither over-tonify nor over-clear, but seek the middle path.
