There are also private people to buy this kind of wire, but the length is limited, because they are all neighbors, all cut a section with a vice, do not charge a penny, this kind of wire itself is relatively cheap, a piece of wire is not worth a few dollars, in order to attract business, be polite to customers, and attract more repeat customers, which is good for the business of hardware stores.

The worst thing is that the four shopkeepers can no longer remember who used to buy iron wire in their hardware store, the hardware store usually does not make money by selling iron wire, the reason why they enter the wire is that someone needs it - as long as someone needs it, even if it is a small iron nail, they have to try to stock up, and the customers who come to the store do not just buy one thing, so as long as the goods are complete, people will come to their hardware store to buy things, because there are more customers who come to the door, so they have no impression of who bought what things. Besides, if the murderer was a local, he would not have been able to come to their hardware store to buy wire. In the south of the old city, you can buy this type of iron wire in any hardware store in Jingnan.

When Chen Jie and Li Wenhua investigated and visited for the second time, Wang Huilan, the wife of Boss Zhao of Xiaochen Hardware Store (located in the 13th camp), provided a person, whose surname was Da, called Da Changjin, and he had bought two kilograms of iron wire in Wang Huilan's hands.

Chen Jie, Li Wenhua and Liu Wenbin conducted an investigation into Da Changjin's progress: Da Changjin bought iron wire to build a kitchen, and his family built a small kitchen in front of the house, and the materials used for the walls were bamboo poles and bamboo fences, and the iron wires were used to fix bamboo poles and fences. When Da Chang entered the house to build a kitchen, he also asked three colleagues to help in the unit.

Ma Minglong led the three of them to Changjin's house to take a look, and the Da family did have a small kitchen, and there were indeed a lot of wires used on the bamboo poles and fences - the wires looked quite new. Neighbors also confirmed that at the end of July, Dajia did ask colleagues from the unit to help build a kitchen, and the three people also found the three colleagues, and their statements were consistent with Da Changjin's statement.

Later, there are only those two old city bricks left, in the north of Moling Road is the ancient city wall, east to the Zhonghua Gate Castle, west to Jiqing Gate, is three or four kilometers long ancient city wall, everyone knows, there are thirteen city gates in Jingnan, it is the most complete city wall in the world.

After investigation and visits, the comrades learned that almost every family living in the area of Moling Road has an ancient city wall in their yards and in illegal buildings. This is also a characteristic of the Chinese people, see the cheap want to occupy, as long as someone digs the ground on the river embankment to grow vegetables, everyone will follow suit, your family divides a piece, my family divides a piece, everyone comes to dig a piece, the city wall brick is a good material for building a house, see others move home, I also move a few pieces by the way, do not move in vain, the good end of the embankment has become a private vegetable garden, the good end of the ancient city wall, was pried into a thousand holes, the public area is a piece of big fat, do not occupy a piece of the heart is uncomfortable, so, your family to build a small shawl, If I build a small kitchen in my house, aren't the bricks of the city wall a good material for building a house? As a result, the ancient city walls, which had stood for hundreds of years, were lost. In the course of human history, civilization and ignorance have always gone hand in hand, and sometimes, the index of civilization can be said to be the peak, and sometimes, the degree of ignorance is staggering. The tragic damage to the ancient city walls is supposed to have happened during that well-known turbulent era.
