In the countryside, there is a man named Zhang San who makes a living by collecting waste. Nowadays, competition in all industries is fierce, and waste collection is no exception. There are many people who collect them, and they are very savvy in selling. At the end of the day, Zhang San makes less than a few yuan.

On this day, Zhang San received a bronze mirror. The bronze mirror looks very old, with some dirt and patina. Zhang San thought that this bronze mirror was very special. If it were sold to antique dealers, the price would be much higher than that of the scrap shop, so he put it aside and did not sell it with the scrap.

When there was time, Zhang San contacted two antique collectors. I met the first person just for bargaining, but didn’t want to sell it. After bargaining, the first person gave five hundred. It’s content to be able to sell five hundred sheets. If the second person gives a little more, he intends to sell it. Unexpectedly, the second person opened his mouth and gave three thousand, which surprised Zhang San. He thought the bronze mirror might be more valuable, so he didn’t plan to sell it. But the man insisted on buying, saying that his friend asked him to accept it. In fact, this bronze mirror is not worth the money, it’s just what a friend wants. Zhang San knows that buyers and sellers will negotiate prices, and he is considered a buyer when he collects scraps. Do business and persuade people to pay attention to methods and methods, just like the current antique dealers, saying that friends are nothing more than finding reasons for lowering prices. Zhang Sanyue didn’t sell it, the more the man wanted to buy it, and the price increased by one thousand and one thousand, but later he was given ten thousand. Zhang San lost his heart, put the bronze mirror away, and said he would not sell anything.

The value of the bronze mirror makes it nowhere to put it. Before, Zhang San just threw it on the pile of debris, but now, it feels unsafe to put it there. Only by holding it in his arms can Zhang San feel the most assured.

In his arms, Zhang San discovered that this bronze mirror turned out to be a treasure.

The first time I took a scrap of a bronze mirror was when I received a part of a machine I don’t know what it was. This part was sold at the price of iron and I made more than 1 yuan. However, Zhang San was surprised to find that he could see the inside of the part. There was a large piece of copper inside the part. He collected the parts at the price of scrap iron, went back to the house and smashed the parts with a hammer, and sold the chiseled copper to the scrap station, earning more than 60 yuan in one go. This is entirely the credit of the bronze mirror. He has experimented that the inside of the parts cannot be seen without the bronze mirror, as long as the bronze mirror is held. The bronze mirror is a treasure detector, capable of penetrating objects and discovering valuable things inside objects that others do not know. With the help of the bronze mirror, Zhang San made many such transactions and made more money, and he gradually became rich.

Once, when Zhang San pedaled a car to hand in waste products, a truck stopped beside him. The driver got off the car and asked Zhang San if he wanted copper. He took a copper ingot from the cart, saying that he hid one when he went to the copper factory to deliver the copper ingot. He wanted to sell it to make some extra money, and the price was very low. If it is normal, Zhang Sanzhun will be fooled. Who won’t take advantage of the obvious advantage? Now he was wearing a copper mirror, and at a glance he could see that the copper ingot had only one layer of copper skin, and inside was black waste slag. Zhang San said no. Then the driver didn’t give up, asking why not so cheap? Zhang San said two words: fake! The scared driverGet into the carriage and drove away. Zhang San has fun! Bronze mirrors can not only detect treasures, but also identify fakes. What a good baby!

But one day, the bronze mirror lost its special function and turned into an ordinary bronze mirror. This began on the day Zhang San picked up the money.

A rag bag lying in the grass on the side of the road will not attract anyone’s attention. But it caught Zhang San’s eyes firmly. I am afraid that only the owner and Zhang San know that there are 5000 yuan in this cloth bag. Humans are really strange animals. In the past, when Zhang San had no money, he felt that too much money was useless, just enough to eat and spend. Now that it’s enough to eat and spend, Zhang San wants to save money to buy an electric three-wheeler to replace his bicycle. In the past, Zhang San would immediately find the owner when he found the money. Now the temptation of 5,000 yuan is too great. This is 5,000 yuan. Is this an electric tricycle!

Zhang San put the cloth bag in his arms, feeling very uncomfortable. He thought that the cloth bag was too dirty, so he took the money out of the cloth bag and threw away the old cloth bag. At this time, the bronze mirror fell out of his arms and dinged and rolled out a long way. Zhang San hurriedly chased after him, but the bronze mirror was picked up by one person. Zhang San suddenly remembered the story of the monkey picking up the sesame seeds and throwing away the watermelon. He is more like that greedy monkey now.

The man picked up the bronze mirror and looked at it. He raised his head and asked Zhang San who was chasing him: “This is yours?” Zhang San nodded and said yes. The man returned the bronze mirror to him and left, suddenly remembering something, and asked Zhang San: “Did you see an old cloth bag?” Zhang San thought, it wouldn’t be so coincidental! But now he is a greedy monkey who gets watermelon and wants sesame seeds. Just say: “No.”

After saying “No”, the bronze mirror has no special function. After trying many times, the bronze mirror really lost its special function.

Later, when Zhang San wanted to sell the bronze mirror, he found a second antique dealer. As the bronze mirror rubbed in Zhang San’s arms for a long time, it had become shiny. The antique dealer looked at it again: “Is this the original mirror?” Zhang San said busy. The antique dealer said: “Even if it is, my friend doesn’t want it now. This, I will give you at most twenty.”

Zhang San found the first antique dealer again. The antique dealer said: “This thing is fake! Can’t you sell it for 5 yuan?”
