He Sold Himself for His Father's Funeral

Dong Yong lost his mother at a young age so he lived with his father, who also died not long later. As he could not afford to give his father a proper funeral, Dong sold himself as a slave to a rich man, who paid for his father's funeral. One day, he met a homeless woman and married her. She helped him weave 300 rolls of silk within a month. Dong sold the silk and used the money to buy his freedom. On the way back, the woman revealed that she was actually the Heavenly Emperor's daughter and was sent to Earth to help Dong gain back his freedom. She then returned to Heaven since her task was complete.
