the story begins with the handsome but poor orphan who lived with his elder brother and sister-in-law. after his parents passed away, the boy's brother inherited the house and land. but all he had was an old ox. as a cowherd, the boy had to work the farm fields with his ox everyday. his daily life routine resembled the story of cinderella (《灰姑娘》).
the seventh daughter of the emperor, also known as the weaving maid, was good at handcrafting, especially weaving clothes. the emperor particularly appreciated her skills of weaving clouds with rainbows to make the world more beautiful.
the cowherd's ox, which was actually an immortal from heaven, made mistakes in heaven and was reincarnated as an ox to toil on earth. one day, the ox suddenly said to the cowherd: "you are a nice person. if you want to get married, go to the brook and your wish will come true."
