Tokyo Station. Although the war has just ended for five years, various municipal construction in Tokyo has entered a period of rapid development. Among them, the buildings of Tokyo Station have become one of the landmark buildings in the city. The original railway station has long been destroyed by the war. After the Japanese cleared the ruins, they rebuilt a brand new railway station: the overall station is like a phoenix reborn in the fire, and the uppermost space is the brain of the station. Every day, the arrival of the train must obey here.

The main body of the station is a three-story building with a spacious waiting hall and a straight and smooth passage that can transport guests to 12 different platforms in the shortest time to wait for the train. Of course, the more appropriate expression of the Japanese nationality is the gorgeously decorated VIP waiting room. All government leaders, financial tycoons, or guests from abroad will be welcomed here to wait and then enter the train's carriage through a special passage.

Ai Fei walked slowly into the waiting hall with his small schoolbag on his back. There were so many guests inside! The people waiting for the bus were sitting or standing, but there was no noise and lively as they were waiting for the train in China. The entire waiting room was quiet. Even if someone spoke, he lowered the sound as much as possible, as if he was afraid of disturbing strangers around him.

He searched inside, looked at the location, and walked towards the duty information room in the waiting room: "That..."

"Ah, I'm sorry, please wait!" A fat guy with a red face - probably the duty monitor - held the phone with one hand, and smiled and bowed slightly to Ai Fei, making a wait gesture to him. The latter took a step back and stood at the door waiting.

After a while, the fat guy finally put down the phone and walked out with a smile on his face: "May I ask..."

"Ah, my surname is Ai, I am a writer. Well, a student writer. Because of the writing needs, I want to do a survey, which is about train operations and schedules. I hope you can get your help."

The fat guy looked up and down at him a few times. He didn't believe that such a childish child would be a writer? Ai Fei saw it and took out his student certificate from his arms and handed it over: "This is my proof!"

"Ah! Sorry, I'm rude." After reading the student ID, the duty monitor finally believed the handsome but childish young man in front of him - he didn't believe that he was a writer, but that he was a student: "Is there anything that needs to be investigated?"

"I want to be with you..."

"Ah, my surname is Nagaoka. Nagaoka Tokuhiro. Ah, please come in and talk?"

"So, thank you... That's it. I want to know how many trains from Tokyo to Kyushu Hakata are from Mr. Nagaoka, and when did they depart?"

"Are you going to Hakata? Please wait..." Nagaoka took out a notebook from the drawer of the desk next to him and read it briefly: "There is a phoenix roster. He left for Hakata at 18:30 in the evening."

"Thank you very much, then, where are you arriving?"

"It will be 28 hours later at 10:22 tomorrow night."

“What a hard journey?”

"Yes! Especially in such a season, it's unlikely that you can even spend the New Year with your family."

"So, which platform should I get on the bus?"

Nagao was stunned for a moment: "Do you even know this?"

"Sorry, this is very important for my writing, I hope to get it."

"Okay. If you have to know, it's on Platform 7."

"Is platform 7?" Ai Fei slowly recorded the information he got in his notebook: "What if he wanted to go to Yokosuka? Can you tell me the number of trains there? Of course, it would be better if he could know where to get on the bus."

This time, Nagaoka didn't even have to open the record book: "Go to Yokosuka? There are the Aika number that is separated by 17:57 and 1801 times at 18:12..."

"Sorry. Just know these two trains." Ai Fei interrupted him with a smile, "So…?"

"Oh, both trains were on the No. 5 platform."

Ai Fei smiled: "Thank you very much. Sorry, there is another last question. Can you see Platform 7 from Platform 5? I mean, when I choose to take the train at 18:12?"

Nagaoka looked at him with a look of surprise: "I saw the Asahiro on Platform 7 from Platform 5. That is to say, is there any car-free between these two platforms? That's what it means!"

"Yes."

"Ah, there are many cars, where can I see it? Okay, wait a moment, I'll study it in detail." This question seemed to have interest Nagaoka: "How could anyone mention such a strange question?" He muttered, while placing the train running table. After a while of complex charts, he heard his surprised and happy voice sounding: "Ah, some are there only a very short time. There are no trains on Platform 5 and Platform 6. You can see the Ashangfeng on Platform 7. Haha, I didn't expect this to happen."

“Can you see it?”

"Yes, but, there's only four minutes."

"Four minutes?" Ai Fei sighed in his heart. Can real evidence be found?

"Yes, that's it." Nagaoka seemed surprised by his discovery and explained to himself: "The Asahiro train drove to Platform 7 at 17:49, and the departure time was 18:30. Stayed next to the platform for 41 minutes. During this time, there were trains entering and leaving on Platform 5 and 6. The No. 5 train heading to Yokosuka on Platform 5 arrived at the station at 17:46 and drove at 17:57. After it left the station, another train No. 1801 arrived at the same platform at 18:01 and then left at 18:12. However, before it left, there was a train No. 341 heading to Shizuoka on Platform 6 at 18:05 and stopped until 18:35, so at this time, the "Asahiro train No. 7 was not seen."

“………?”

"Don't understand? I'll draw a picture for you to see."

Nagaoka was quite enthusiastic, but he didn't know that Ai Fei's mood was not on this! He got the most important message and was completely enough for his writing. However, the old man was very enthusiastic, so he couldn't refuse rashly. He took the simple drawings drawn by the other party for himself and expressed his gratitude to the old man again. Ai Fei embarked on the journey back.
