introduction

"Mom and Dad, look, what a big cow!" A little boy about ten years old took his parents' hands and shouted happily.

It was about seven o'clock in the evening, but the streets of Ningzhen were crowded. Come and go.

On both sides of the street, which is not wide, it is crowded with people, and the yellow light from the street lamps shines warmly on people. The street trees are covered with colorful lanterns, which change colors and shine in a regular manner. In the middle of the street, there was a long line walking unhurriedly.

This team is composed of more than a dozen people in a group, and a large lantern is pushed forward together. The lanterns are all shaped like cows, all of which are five or six meters long.

"Xiaoyu." The child's mother smiled and said, "This is not a cow, this is called a cow lantern, first make a cow frame, wrap cloth of various colors on the outside, and put a lot of light bulbs inside, and then it becomes a cow lantern." Put this cow lantern on the trolley, and it will light up when the electricity is turned on. ”

"Then why are you called a cow lantern? Also, why are they all cows, and there are no flowers? The little boy asked with interest.

The child's father looked at the little boy, smiled at the mother, squatted down and looked at the little boy and said, "Jinyu, this lantern is just the name of our locals, it was called like this a long time ago, and it has been passed down forever. Cow, have you forgotten what year it is? ”

"I know, the Year of the Tiger is the Tiger Lantern, and the Year of the Dragon is the Dragon Lantern." The little boy exclaimed excitedly.

"That's smart!" The child's father smiled and touched the little boy's head, then stood up and looked at the cow lantern that had just passed in front of him, but his eyes became a little gloomy, "It's just that this activity of welcoming the lantern doesn't know if it can be welcomed in the future." ”

The wife took her husband's hand and whispered, "Don't think too much, old man, let's continue to watch." ”

"Hmm." The husband squeezed his wife's hand.

At this moment, a deafening explosion suddenly sounded ahead, and then the crowd began to move desperately towards the three of them, mixed with screams.

"Dead man! Dead man! The lanterns are blown up! Yes! ”

"Don't step on me, ah! Help me! ”

"Mom, Mom, where are you? Whining! ”

"Husband, husband, get up quickly! Yes! There's a lot of blood, don't scare me! You speak! ”

Even the air seems to be stained with scarlet.

"Students, the next thing we want to visit is the Humanities Museum, the theme of the Humanities Museum this time is not the boxwood carving we saw last time, but the Ningzhen Festival Lantern."

There was a chubby male tour guide, who was introducing to the classmates behind him in his magnetic voice, "Look, classmates, what I have in my hand now is the most ordinary holiday lantern." "The guide was holding a foam cake with lots and lots of little grooves in it, distributed in a circle, with several rings. A long line of lights with countless small bulbs placed in sequence in grooves on the foam board.

The guide plug from the string of lamps on the foam board plugged into a socket on the table next to him, and the lamp immediately flashed with colorful light at regular intervals.

"It's so beautiful!" The students let out a burst of exclamation.

"And whatever!" The guide smiled and pressed the button on a small controller that was also placed on the foam board, and the flickering pattern of the festival lights changed, and it looked like they were flashing in circles. The tour guide pressed it again, and the flickering pattern of the festival lights changed again, this time changing one color after another regularly.

"Wow!" The students let out another burst of exclamation.

"It's called the Circulator of the Festival Light." The tour guide pointed to the small controller, "Every time you press this circulator, the glow pattern of the festival lights will change, and ah, don't think that the festival lights are such a simple thing." We can also take out the string lights inside and hang them on the wall in any shape you want, or hang them on the trees. ”

"But isn't it easy to buy these little lanterns on the Internet?" A chubby male classmate said something.

"Zhou Hao, it's not that simple." Jiang Tian, who was beside Zhou Hao, patted him on the shoulder and said, "That's right, the technology is simple, but it's a culture, understand?" ”

The tour guide answered with a smile, "Yes, this classmate is right, festival lights have become a kind of culture in Ningzhen." Moreover, the festival lights of Ningzhen are also one of the most important production areas of festival lamps in the country, and Ningzhen is known as the hometown of Chinese festival lights! ”

"And." The tour guide said mysteriously: "I also said just now, just now we only saw the most basic festival lights, and then let's see some magical festival lights." With that, the tour guide led the students into another room of the exhibition hall.

"Wow!" The crowd erupted in amazement again.

In front of everyone's eyes, there was a cow more than two meters tall.

"Hehe, this is called a lantern in Ningzhen, and what you are looking at should be called a cow lantern to be precise."

……

"I said Jiang Tian, did you really decide to run that far just to take a look at the festival lights in Ningzhen? Well, I think it's too late for you to regret it now. Zhou Hao looked at the people coming and going around and said helplessly.

At this moment, Jiang Tian was standing in the send-off area outside H East Railway Station, carrying a backpack on his back, and in front of him stood Ni Gang, Zhou Hao and He Yuexin, who came to see him off.

"Hey." Ni Gang patted Zhou Hao on the shoulder, "Don't forget, our group still has a social practice activity." This time, it's rare for someone to run for a boring trip, and you don't need us to spend money, so you can be content. ”

"Okay, Jiang Tian." Zhou Hao looked at Jiang Tian with an awe-inspiring expression, "Since you have shouldered the heavy responsibility given to you by our organization, you must be worthy of the organization's attention and expectations for you, ok, what, the train is about to leave, let's go." After that, he pushed Jiang Tian.

"I'll you old boy." Jiang Tian scolded with a smile.

He Yuexin looked at Jiang Tian and said lightly, "Have a good trip." ”

"Hmm." Jiang Tian raised his eyebrows and nodded.

……

Ningzhen is a small mountain town located in the west of T City, our province. In the past, Ningzhen relied on its cultural characteristics - festival lights, which occupied an advantage in the competition in the market, and even exported to overseas for a time, making a lot of money! However, a few years ago, the market for Ningzhen festival lights suddenly shrank sharply, and several Ningzhen festival lamp factories closed down, and the festival lamp industry was not as good as before.

And the cause of this series of incidents was an explosion that occurred at the Lantern Festival parade in Ningzhen.

Since getting on the train, Jiang Tian has been looking at a yellowed newspaper in his hand:

Last night, there was an explosion at the Lantern Festival parade in Ningzhen, and it caused a serious stampede!

The content of the article is already familiar to Jiang Tian. Two large lanterns suddenly exploded and caught fire during the Lantern Parade, which caused panic among the people due to the large fire, and the density of the rally was very large, and a stampede occurred in a panic. The accident killed thirteen people and injured nearly seventy. The results of the police investigation are very simple, the quality of the lantern is not up to standard, the internal circuit is short-circuited, and the high temperature of the wire rod causes an explosion and ignites the lantern. Afterwards, several headlamp factories that made the lanterns lost a lot of money and were close to bankruptcy, thus affecting the festival lamp industry in Ningzhen.

"In recent years, the festival lamp industry in Ningzhen has slowly recovered, and the re-emergence of festival lights in Ningzhen is still very good." Jiang Tian thought, "By the way, it's quite interesting to take a look at the production of festival lights in Ningzhen." ”

"However, that explosion ......" Jiang Tian fell into deep thought.
