Legend has it that a long time ago, there lived a fishmonger selling fish in Paifang Hutong. The fishmonger set up a stall to sell fish under the stone archway. There are many people coming and going in the aisle, and they all bought some fish from the fishmonger to eat at home. For a time, the business of fishmongers was quite prosperous. But after a long time, fishmongers began to use their brains. When selling fish, the fishmonger pressed the beam head with his little finger, which was clearly fourteen Liang (sixteen Liang was a catty in ancient times). He pressed it gently with his little finger, and then moved the weight to a catty of stars. The buyer saw that the scale was a little high and could not set the stars, so he happily bought the fish home.

The fishmonger thought he was clever, but after a long time, he was discovered by a shrewd man. People began to talk about it one after another, but instead of repenting, the fishmonger thought he was better than others, ignored others' attention and turned a deaf ear to his deceptive business.

One day, a fishmonger was selling fish under the archway, and an old lady came up to him with a bag of fish in her hand: "Fish seller, I just bought a catty of fish from you. When I arrived at that store, it was two taels of silver. Is there something wrong with your scale? "

The fishmonger knew it was bad when he found you. He saw several people who had bought fish put their money back in their pockets. Seeing this, the fishmonger looked up at the stone archway and swore, "My fishmonger has sold fish for so many years. If he loses weight once, let a corner of this archway fall and kill me! "

As soon as the voice fell, I heard a "click" sound, which startled people. When they came to their senses, the corner of the stone archway pointed by the fishmonger just now really fell off, and the fishmonger was killed by a big stone corner.

This legend has been passed down until now, and the big stone corner that fell from the top of the stone archway and killed the fishmonger is still lying under the archway.

"There is a god on the head of three feet", no matter what people do, it is for themselves. Good is rewarded with good, and evil with evil. This is the law of nature. I hope people can get some inspiration from this folklore.
