Following the flow of people, everyone came to the intersection 50 meters away from the entrance of the main Christmas market. He Yuanjin's sharp eyes saw a brightly lit area 100 meters opposite the entrance. The crowds of people were rising and falling under the lights. She watched intently, but most of them were children.
"What's that over there? It's very lively." He Yuanjin asked Lei Lanting, but Lei Lanting threw the question directly to Dong Qiangqiang without thinking.
"Trier was once a prosperous trade center and administrative center of the Roman Empire, second only to Rome in status. Even the Western Emperor at that time chose to settle here. In order to protect the emperor, the Romans used more than 7,000 light stones around 170 AD. The city wall that protects the city was built of high-quality sandstone. The building that looks like a castle is actually a city gate, just like the nine gates of BJ. As the times change, the city gate is used for many purposes. In the 11th century, it was the site of the Hermitage West The residence of the Burmese monks. After his death, the city gate was converted into a church. In 1803, during the reign of Napoleon, the church was dissolved and the city gate restored to its original appearance. Due to its solid structure, it has been preserved to this day. But since the Middle Ages From the beginning, its appearance gradually became gloomy. Since the original name of the city gate is no longer known, people called it the Black Gate based on the color of its outer wall. However, Chinese students jokingly called it the Big Black Gate. The Big Black Gate is Germany’s current The best-preserved Roman city gate known to the world has been included in the World Cultural Heritage List by UNESCO. There are usually some display boards and roll-up banners in the open space in front of it to introduce the city's history, culture, and historical sites. Every Christmas The festival became the ice rink and carousel that it is today.”
Before he finished speaking, the lights around the ice rink simultaneously faded from blue to orange. The actress playing Rapunzel stepped onto the ice rink silkily to the soft music and danced. Her gentle movements attracted the attention of many boys and girls outside the ice rink. Her eyes lit up, and time seemed to slow down with every movement she made. Santa Claus, who transformed into a conductor, sat in the sleigh-shaped ticket booth with a smile, delivering candies as admission tickets to the hands of ticket buyers, while the carousel brought horseback to the descendants of the horseback people. First experience in life.
Lao Bai quietly said something to Tong Lele, and Tong Lele's face immediately turned as red as a tomato. She hit him on the arm pretending to be angry, while he looked at her lovingly, his eyes full of tenderness.
"Go up and take a look." Dong Qiangqiang suggested.
After entering the door and going up the stairs, everyone except Dong Qiangqiang discovered that not a single light was on in the black door from top to bottom. Whether it was the stairs, corridors, or inner rooms, they were all dark. The only light source was from the door. The lighting of the ice rink and carousel leaked in through the holes in the city wall.
"Let me go, why is it so dark here?" Lei Lanting complained in confusion, "The Germans won't even save this little money on electricity, right? If it can't be done, just give them a solar lamp. Did you drop your book bag just now, Old Dong? Are you fooling us? The real reason it’s called the Black Door is that there are no lights here, so whoever comes in will have a black eye.”
Before he could finish speaking, Lao Bai, who was walking at the end of the team, sneered and said disdainfully: "Ignorance."
"Hey, Lao Bai, am I wrong? What do you see here? You can't see anything with a 15-euro ticket. Don't you think you've been cheated?" Lei Lanting argued.
"Thank you for being a tour guide for a few months." Lao Bai continued to say sarcastically.
"The Germans did this not because of picking, but to prevent the light from corroding the city wall. You can see that the lights of the ice rink outside are also irradiated towards the side that is not the black gate." Dong Qiangqiang explained.
Everyone turned their attention to the outside of the wall, and then they discovered that the lights of the ice rink were exactly as Dong Qiangqiang said. They were all facing away from the black door. If Dong Qiangqiang hadn't said anything, no one would have noticed.
"Hey, how many light bulbs can corrode the wall?" He Yuanjin patted the wall next to him in confusion, "But aren't these all stones? The light from ordinary light bulbs is not a laser, so can it still have a corrosive effect? "
"In layman's terms, stones absorb light, and light contains heat. If it is continuously illuminated, the stone will continue to absorb heat, just like a stone block under the summer sun. It absorbs heat during the day and releases heat at night. It is not only harmful to It has an impact on its own lifespan and will also have an impact on its surrounding environment, so the Germans strictly limit the lighting of the monument itself and within a certain range next to it. And not only the Germans do this, but the French do too. Last time you went to the Louvre Didn't Gong pay attention? It's the same reason not to let the flash go when taking pictures of famous paintings." Lao Bai questioned, "Lei Lanting, your professional skills are worrying. I originally planned to let you take Lu Shan, but you are half jealous yourself. , isn’t it a mistake to ask you to lead people?”
"Hey, Lao Bai, don't go online. What I said is actually to test the old director. I'm afraid that he will be unfamiliar with the business after not leading a group for a few months. Hey, we are at the top of the building, everyone should be careful where they step." Lei After Lan Ting finished speaking, he ran toward the top floor.
"This guy..." Lao Bai shook his head and sighed, "He's still so uncomprehensive."
The wind on the rooftop was as cold as the icy water of the Moselle River, whipping everyone around like a whip. Everyone couldn't help but wrap up their cotton clothes and looked curiously towards the city center.
Dong Qiangqiang saw the layers of unmelted snow on the colorful roofs on both sides of the street being blown up by the wind, naturally blending into the dense clouds and smoke above the Christmas market. In the pale white mist, kiosks with unique decorations are scattered all over the place, extending to the end of the market, like twinkling stars in the night sky. A several-story Saxon spruce Christmas tree stands in the center of the city center, covered with red Christmas balls and string lights. On the exterior wall of the building behind the tree is an oversized Christmas calendar composed of dozens of windows. The Christmas market was bustling with people, and all kinds of vendors came to greet them. Everyone was smiling, and the joy was spread to everyone in the venue.
Looking at the fairy tale world-like Christmas market in front of him and the endless flow of people talking, laughing, singing and dancing, Dong Qiangqiang couldn't help but recall the scene when he and Du Lan went to find Lao Bai at this time last year. Who would have thought that one year Later, Lao Bai and Tong Lele were about to get married. He felt very relaxed, and he felt like someone who had been constipated for a long time finally took advantage of Kaiselu.
After a long time, I heard Lei Lanting say "Hey". Everyone said nothing, still enjoying the night view around them comfortably.
"Hey, Lao Bai, have you seen that church over there?" Lei Lanting asked.
"Who can't see it when it's so bright?" Lao Bai said angrily.
"I have a question. According to what you and Lao Dong said, if a light bulb is installed and there is light, the light may pollute the building. Then let me ask you, isn't the Trier Cathedral considered a cultural relic? Those ancient houses next to it Don’t the houses have hundreds of years of history? Why can you see so many lights inside and outside the cathedral? The city center is now brightly lit, so there is no light pollution in it? You are well-informed, so tell me what this means.” Lei Lanting retorted unconvinced.
"..."
Lei Lanting's question cannot really be said to be arbitrary. Even Lao Bai couldn't help but be speechless for a moment, not knowing how to explain it.
“Perhaps we don’t know what new technologies are used in these lighting equipment, or these lightings do cause light pollution.” Dong Qiangqiang admitted, “Maybe churches are an exception.”
"Why is the church an exception?" Hearing Dong Qiangqiang admit that his theory was lacking, Lei Lanting was very happy and immediately pursued the victory. This was the first festival that he and He Yuanjin became boyfriend and girlfriend. He needed words to bring victory. face.
"Because..." Dong Qiangqiang deliberately let it slip, "God said something."
"What words?"
"There must be light," Dong Qiangqiang said every word, "and then there will be light."
Everyone was stunned. After a second, Lu Wei was the first to react. He clapped his hands and laughed, showing a smile that Dong Qiangqiang had not seen all night. Then several people reacted and clapped in agreement.
"You are still so humorous." Lu Wei came to Dong Qiangqiang's side and praised, "Well said."
Dong Qiangqiang was very happy. He seemed to see the girl in front of the library again.
"What are they laughing at?" He Yuanjin asked Tong Lele beside him in confusion, "I don't understand where the laughter is."
"What Dong Qiangqiang just said was the first sentence of the Bible, a good homophone."
"What's the cola?" He Yuanjin stuck out his tongue, "Isn't it just a word?"
Tong Lele sighed: "Xiao He, I have to say that you and Lei Lanting really match each other."
