After historical development, it has been endowed with the beautiful love legend of "Cowherd and Weaver Girl", making it a festival symbolizing love, so it is considered as the most popular festival in China.

As for the story of the Cowherd and the Weaver Girl, it is a famous folk love story in ancient China. It's about an orphan cowherd who lives on her aunt. Abused by his brother and sister-in-law, he was forced to leave home and rely on an old cow to plow the fields to support himself. One day, the weaver girl and fairies came to the world to play and bathe in the river. The old cow suddenly spoke, persuaded the cowherd to meet each other, and told him that if the fairies didn't go back before dawn, they would have to stay on earth. So the cowherd stayed by the river to see the seven fairies. He found that the youngest fairy was very beautiful, suddenly fell in love with it, remembered the old cow, and quietly took away the little fairy's clothes. The fairies took a bath and prepared to return to heaven. After a while, they fell in love, and the little fairy married the cowherd and never wanted to go back to heaven. After marriage, they farm and weave, have a son and a daughter, and live a very happy life. Unexpectedly, the Emperor of Heaven discovered this matter and ordered the Queen Mother to escort the Weaver Girl back to heaven for trial. The old cow couldn't bear to see their wife and children separated, so she touched the horn on her head and turned it into a boat for the cowherd to chase with her children. On the verge of catching up with Weaver Girl, the Queen Mother suddenly tore off the golden hairpin on her head and drew a rolling galaxy in the sky. Cowherd can't cross the river, so he can only look at the river and cry with Weaver Girl. Their faithful love touched magpies, and countless magpies flew in and built a colorful bridge on the Tianhe River with their bodies, so that the cowherd and the Weaver Girl could meet on the Tianhe River. The Emperor of Heaven had no choice but to allow the Cowherd and the Weaver Girl to meet at the Magpie Bridge once a year on July 7th, and the magpies would be around. Cowherd and Weaver Girl will meet on July 7th every year.
