Why do you have to find a fork in the road to burn paper money?

Not a fork in the road, a fork in the road. Only when you can't find the fork in the road can the ghost postman find the money you gave to the world earlier and receive it earlier.

There is a little story:

"After Cai Lun invented paper, the difficulty of writing was solved, and papermaking became a profitable business. Sister-in-law Cai Lun's heart itched, forcing her husband Cai to go back to Cai Lun to learn how to make paper. Cai Hui couldn't stand his wife's urging and rushed back to the village to open a paper mill without learning technology. Without good technology, you can't make good paper naturally, so it's difficult to sell it. The couple looked at the piles of unsalable paper and were very anxious. After a while, Cai Hui and his wife came up with a clever plan.

In the dead of night, the neighbors suddenly heard Cai Hui crying, and everyone came to ask what had happened. Cai Hui said sadly, "My wife quarreled with me about papermaking, and she hanged herself." Cai Hui knelt in front of his wife's coffin and cried her eyes out. Neighbors also came to help. "It's all these broken papers!" At this time, Cai Hui, who was crying her eyes out, burned paper and cried in front of everyone, and the coffin made a noise. He pretended not to hear, but burned and cried. I heard my wife shouting in the coffin, "Open the door, I'm back!" " This is shocking. Everyone looks at me, and I look at you. Finally, I got up the courage and opened the coffin lid. Cai Hui's wife sat up and sang eloquently, "Money makes the mare go? Fortunately, paper turns into money to do business in the underworld; My husband doesn't burn paper. Who wants me to go home? " Then he said, "I was a ghost just now, and now I'm a man." I gave Yan the money my husband gave me, and he gave me another sum. " Cai Hui deliberately said, "But I didn't send you money?" She pointed to the pile of burning paper and said, "That's the money you sent. The world uses copper as money, and the underworld uses paper as money. " Everyone knows that burning paper is still so useful that they are rushing to buy it. Cai Hui gave everyone a big bag for free. As soon as the news spread, it spread to hundreds of families. Within a few days, customers flocked to buy all the newspapers in the room. Since his wife returned to Yang on 1 October1day of the lunar calendar, people burn incense and paper as ghosts on this day, and this custom has been passed down to this day. "

Crossroads are places where ghosts go from south to north. At the intersection, it is convenient to mail, because there are postmen in the underworld.
