What is the origin of Valentine's Day in China?

The Origin and Allusions of Valentine's Day on Qixi Festival

The ancient astronomical culture in China has a long history and is profound. The ancients began to explore the mysteries of the universe from a very young age, and inferred a complete and profound astronomical culture from this. Cowherd and Weaver Girl is a typical example. The legend of Cowherd and Weaver Girl on Tanabata originates from people's worship of natural phenomena.

As early as ancient times, the ancients who pursued order not only planned the sky orderly, but also corresponded the stars with the ground one by one. This correspondence is called "dividing the stars" and "dividing the land" in astronomy. Simply put, the ancients mapped each constellation in the sky to the physical geographical area of the earth.

The purpose of ancient separation was mainly to coordinate the astrological theory in astronomical astrology. In the ancient constellation system, "Taurus" is composed of six stars, located on the east bank of the Milky Way, like two inverted triangles, which are distinctive when they go up and down, but the triangle above is bigger and brighter.

The triangle below lies on the ecliptic. These stars form a cow with two horns on its head but only three feet, so the ancients called it "morning glory".

There are nine little stars in the south of the cow, which constitute its farm-Tian Tian. Looking south, near the south horizon, there is nine planets in Jiukan, which is a low-lying water storage area for irrigating farmland. East of Niuxing is Luo Yan, a water conservancy facility similar to a reservoir. Vega lies to the north of Taurus.

Vega I is the fifth brightest star in the sky, second only to arcturus, so it is often called Vega directly. The ancients called "Niu Xing" and "Weaver Girl" Cowherd and Weaver Girl.

According to folklore, on the evening of July 30th every year, the Weaver Maid and Cowherd will meet at the Magpie Bridge in the sky. The Weaver Girl is a beautiful, clever and clever fairy.

On this night, facing the bright moon in the sky, the girls put on seasonal fruits, prostrated themselves in worship, and begged the gods to give them spiritual wisdom and dexterous hands to make them skilled in knitting, and even begged for the coincidence of love and marriage. Countless beloved men and women in the world will pray for a happy marriage at night, when the night is quiet and the sky is deep.
