七夕節的由來源自於牛郎織女星宿和牛郎織女的愛情傳說。
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.
織女和牽牛是天河中相近的兩顆星宿，兩者並沒有什麽關聯。直到漢朝時，這兩顆星宿才被轉化為具體人物。牛郎和織女就是從牽牛星、織女星的星名衍化而來。
傳說古代天帝的孫女織女擅長織布，每天給天空織彩霞，她討厭這枯燥的生活，就偷偷下到凡間，私自嫁給河西的牛郎，過上男耕女織的生活，此事惹怒了天帝，把織女捉回天宮，責令他們分離，只允許他們每年的七月七日在鵲橋上相會壹次。
他們堅貞的愛情感動了喜鵲，無數喜鵲飛來，用身體搭成壹道跨越天河的彩橋，讓牛郎織女在天河上相會。

七夕節的民間習俗有：
1、香橋會
在江蘇宜興，有七夕香橋會習俗。每年七夕，人們都趕來搭制香橋。入夜，人們祭祀雙星、乞求福祥，然後將香橋焚化，象征著雙星已走過香橋，歡喜地相會。這香橋是由傳說中的鵲橋傳說衍化而來的。
2、接露水
浙江農村，流行用臉盆接露水的習俗。傳說七夕節時的露水是牛郎織女相會時的眼淚，如抹在眼上和手上，可使人眼明手快。
3、穿針乞巧
穿針乞巧，女子比賽穿針，她們結彩線，穿七孔針，誰穿得越快，就意味著誰乞到的巧越多，穿得慢的稱為“輸巧”，“輸巧”的人要將事先準備好的禮物送給得巧者。
