Friend's Personal Experience

I have a friend who really loves fishing. One night, as usual, he went fishing with two other friends. They barely caught any fish that day. When they were about to go home, my friend's fishing rod suddenly moved. But when he reeled it in, there was nothing there. That night, my friend started having diarrhea. It was so severe that he had to go to the emergency room in the middle of the night. He was hospitalized for three days. But they couldn't find anything wrong. It was so bad he couldn't even go to work. Then, his sister, who has the ability to see ghosts, told his older brother: 'Brother, it looks like a girl is following behind our second brother. And she looks very angry.' So my friend went to see a former teacher of his. That teacher took him to a very powerful master nearby. The master immediately drew him a talisman. And he strongly advised him to stick the talisman on his door. He said the master asked him if he had been to any waterside places recently. He said he had been fishing recently. Then the master said he had encountered a 'North Wind Evil Spirit' (煞神). He is very fierce and can kill people. That's why he had been having diarrhea.
