Stories and legends of cowherd and weaver girl

Cowherd is a god cow in the sky, and he was demoted to the world for violating heaven. On the earth, he became a poor peasant boy and formed a deep friendship with a sick old cow. With the help of the old cow, the cowherd got to know the Weaver Girl in the sky, and they hit it off. Later, the weaver girl secretly descended to earth and became the wife of the cowherd. They lived a happy life, and the Weaver Girl distributed wild silkworms brought from the sky to everyone, teaching them to raise silkworms and spin silks and weave bright silks.

However, this wonderful life did not last long. The Emperor of Heaven was very angry when he learned that the Weaver Girl had come down to earth privately, and ordered the Weaver Girl to return to the Heavenly Palace. Cowherd and Weaver Girl were forced to separate, and they were only allowed to meet on the Queqiao once a year on the seventh day of the seventh lunar month.

The faithful love of the Cowherd and the Weaver Girl touched the magpies, and countless magpies flew to build a magpie bridge to let the Cowherd and the Weaver Girl meet on the Tianhe River.
