七夕节的由来源自于牛郎织女星宿和牛郎织女的爱情传说。

The Weaver Girl and the Morning Cattle are two similar stars in the Tianhe River. There is no connection between the two.

Until the Han Dynasty, these two stars were transformed into specific characters. The Cowherd and the Weaver Girl are derived from the star names of the Altair and the Vega.

Legend has it that the granddaughter of the ancient Emperor of Heaven was good at weaving, and weaved the sky every day.

She hated this boring life, and secretly went down to the mortal world, privately married to the cowherd of Hexi, and lived a life of men and women.

Angry the Emperor, the Weaver Girl was taken back to the Heavenly Palace, and they were ordered to separate. They were only allowed to meet on the bridge on July 7 each year.

Their strong love and affection moved magpies, countless magpies flew, and used the body to form a color bridge across the Tianhe River, allowing the Cowherd and the Weaver Girl to meet on the Tianhe River.

织女和牵牛是天河中相近的两颗星宿，两者并没有什么关联。直到汉朝时，这两颗星宿才被转化为具体人物。牛郎和织女就是从牵牛星、织女星的星名衍化而来。

传说古代天帝的孙女织女擅长织布，每天给天空织彩霞，她讨厌这枯燥的生活，就偷偷下到凡间，私自嫁给河西的牛郎，过上男耕女织的生活，此事惹怒了天帝，把织女捉回天宫，责令他们分离，只允许他们每年的七月七日在鹊桥上相会一次。

他们坚贞的爱情感动了喜鹊，无数喜鹊飞来，用身体搭成一道跨越天河的彩桥，让牛郎织女在天河上相会。
