A young man by the name of Zhang Balang had an affair with one of his maids, but as soon as he was married he abandoned her. This maid fell into a deep depression and soon died of misery.
"I will never forgive Balang for the way he has treated me!" she said with her dying breath.
Then all of a sudden her eyes popped open again and she said, " Balang carries an extremely strong karma, so it will be difficult to exact my revenge on him personally. I think I'll go for his wife instead!"
Before two years were up, Balang's wife had died from complications during childbirth.
