When the sun crosses the celestial longitude of 135° on August 7, 2025, nature quietly begins autumn's prelude.

As one of the "Four Commencements" in China's 24 solar terms, Liqiu (Beginning of Autumn) marks not just a climatic turning point—where summer heat yields to crisp air—but also embodies the agricultural wisdom of "grain ripening."

At this threshold between seasons, let us embrace an ancient invitation to both introspection and harvest, guided by millennia of celestial rhythm.

Liqiu (Beginning of Autumn) carries profound historical significance dating back to the Zhou Dynasty (1046-256 BCE). On this day, the emperor would lead nobles and officials to the western suburbs for the Autumn Welcoming Ceremony, offering sacrifices to Shaohao (the Celestial Deity of the West) and Rushou (the God of Harvest).

This ancient ritual reflects: 

1️⃣ Harmony with nature – Formal acknowledgment of seasonal transition

2️⃣ Agricultural reverence – Rushou's association with autumn harvests

3️⃣ Cultural legacy – Institutionalized celestial observance

The ceremony's western orientation symbolically aligned with autumn's elemental metal and directional associations in Chinese cosmology.

Liqiu's significance grew alongside calendar system developments. As Dong Zhongshu noted in Han Dynasty's Luxuriant Dew of the Spring and Autumn Annals: "The Autumn Equinox balances yin and yang, bringing equal day/night and moderate temperatures." Though describing the equinox, this reflects ancient China's precise seasonal understanding.

Three Phenological Signs of Liqiu 

The ancient Chinese divided Liqiu (Beginning of Autumn) into three pentads, each vividly capturing nature's subtle transformations during this season-like movements in a beautiful symphony of nature.

Summer’s scorching winds are gone—now gentle breezes bring the first cool hints of autumn. Like soft messengers, they sweep over the land, chasing away summer’s leftover heat and bringing the long-awaited refreshment and calm we’ve been waiting for.

As day-night temperature differences grow, a layer of crystal-clear dew forms on the ground and plants each morning. These dewdrops, like nature’s inlaid pearls, shimmer with colorful light in the sun. They are autumn’s tears, holding nostalgia and reluctance for summer.

Autumn cicadas are unique to fall. Unlike the noisy summer ones, their chirps feel more desolate and mournful. In the third pentad after Start of Autumn, they seem to sense the shifting seasons—singing earnestly on branches, as if making a final farewell to the world.
