"In other words, what you saw and heard before is likely just your personal hallucination?"

“…… Call...... I...... I do not know...... No, it's not ......"

"Mr. Li, I still say the same thing, just like that, we can't conclude that this is a supernatural event, and it is more likely that something is wrong with your personal body or spirit."

“……”

"Mr. Li, are you okay?"

"I don't know...... I...... Am I crazy? ”

"It takes the hospital to make a diagnosis."

“……”

"Does your family know about this?"

"No ......"

"You can talk to your family and go to the hospital for a detailed check-up with them. Alternatively, you can change your environment and take a period of leave. If you can't avoid the problems you are experiencing now, you may want to consider changing jobs and leaving campus. I know it's a big life decision that will affect your life, but you look really bad right now, and if you continue like this, it's only going to get worse. This is just my personal opinion......"

"No, isn't it an evil one?"

"This possibility is not completely ruled out. Well, we'll take a look at the school where you work, and you'll go to the hospital for a check-up. Is that okay? ”

"I think...... I think I really saw it...... That kid, that boy......"

"So, did you notice any of his distinguishing features at the time?"

Feature...... So tall, more than one meter two, not fat or thin, wearing a sweatshirt and sweatpants, not a set, sports mountain is a black zipper shirt, sweatpants...... Blue, blue sweatpants, you know? There's a white border here. ”

"Hmm. These don't count as crucial clues. ”

“……”

"Is there anything else you can remember?"

"No, that's all."

"So, what do you think of my proposal?"

"Hmm...... Isn't it really a ghost? ”

"It's not certain yet, but we think it's very unlikely."

"Oh......"

"You expect to be a ghost?"

"No, it's not! Of course not! I didn't expect to see ghosts, but ...... But it's crazy...... I don't think I'm in a bad head, I'm normal, it's just this kind of thing......"

"Mr. Li, we're not saying you're crazy. You may have a physical condition, fatigue, illness...... It's also possible that mental stress is causing you to hallucinate. ”

"What pressure can I have as an art teacher? Alas......"

"Anyway, let's do a check-up first."

"Hmmm......"

Analysis of audio files, 12 March 2002. Audio files.

“…… It was five o'clock, and all the students in the school were gone, and I was about to leave, when I heard a voice......"

click！

"There was no sound in this man."

"Sure enough, he still has his own problem."

"At least it means that he wasn't haunted by a ghost."

"Let's see what happens."

On March 13, 2002, I went to Bihai Primary School, where the client worked. Audio files.

"I'm sorry, please let them in, they're looking for me."

"Teacher Li, is this your relative?"

"Hmm. They are from the normal school and want to come and see the school. ”

"Oh - are you looking for an art teacher? Teacher Xu is going to take maternity leave, right? ”

"Hehe, they just came to see, and they don't know where they will go after graduation."

……

"This way. Now in class, you guys are quieter. ”

"Well, okay. What are the classrooms you see? ”

"The first two rooms on the second floor, and the two over there."

"Hmm."

"How, how?"

"You mentioned the library before, right?"

"Yes, on the fifth floor, up here."

"This is where the boy took the stairs?"

"Huh? No, it's the stairs over there. ”

"Then let's go over there and have a look."

……

Da, da, da......

……

"That's it, my office is here, and when I come out, I can see the classroom opposite. That's where the boy runs, and this wall is in the way, and I don't see ......."

Da, da, da......

"You...... Do you think he could ...... from this side window?"

"It's just a matter of ruling out all possibilities. For now, there are no ghosts here. ”

"Ah......h

"Let's go to the library."

"Oh, good."

……

Da, da, da......

……

"The library is in front of it, and the door should be locked now. However, the teacher in the library may be in the ......"

Knock knock.

"The door is locked, he probably isn't in the library."

"The northwest corner, is that over there?"

"There's a library over there, and it's all over here."

"What's in that corner?"

"This ...... I really don't know ...... this."

"Teacher Li?"

"Ah, Mr. Zhang."

"You're ......"

"This is my relative, and his classmates, all from normal school. They're just about to graduate, so come to the school and see ......."

"Huh? Doesn't the school have an internship scheduled? ”

"It's arranged, it's just high school, and they want to see elementary school. I happened to be an elementary school teacher......"

"Oh. Elementary school is different. ”

"Hello, Mr. Zhang. I heard that you are a teacher in the library here? ”

"Well, you're welcome, you guys come in and have a look."

Whoa......

"Thank you so much."

When the ......

"These keys belong to the library?"

"Some are office. Library keys are also quite a bit of them. ”

Click, click, click......

"As you can see, our school library is still quite large, and some books are not put out, in the back room."

"Hmm. Is there a warehouse in the back? ”

"It's not a warehouse, it's just a room. Some of the books are older, a long time ago. Our school also has a long history. New books are also purchased every year. The kind of children's version of the masterpiece, every year there are new editions released by the publisher, as well as classic fairy tale books, teaching aids...... So accumulate and there are too many books. Half of the reading room, half of the stacks, and the bookshelves have to take care of the children, and the design is very low, so many books can't fit there. ”

"Hmm. It's very different from the library in high school. ”

"yes."

"Can you take a look at the warehouse?"

"Oh? Yes. There's a lot of dust, though. ”

"It's okay."

"I'm sorry for you, Mr. Xu."

"Nothing. …… What did you study? Which subject? ”

"Language."

"Oh. Chinese teacher, it's good. If you teach the upper grades, you can actually do it in elementary school, but the children in the lower grades are more noisy. But the younger ones are also afraid of the teacher, and as soon as the teacher appears, he will be obedient. ”

"Hmm."

"It's better to be a teacher in high school, it's hard work, but it's also a lot of money. And it's much easier for high school students to communicate, at least than for 10-year-olds. ”

"Hmm."

"Mr. Xu, there seem to be a few books missing from the bookshelf over there?"

"Which side? Oh, that one was borrowed by a teacher. It turned out to be a fairy tale series in country E.,There's a teacher who wants to open a class and borrows it.。 ”

"Can teachers borrow books too?"

"yes. The teacher does not have a library card, and the borrowing of a book is to register. ”

Whoa...... Knock! Squeak –

"Well, this is the warehouse. The ventilation is not good, and some of the books are really old, and they smell bad. Alas......"

"Mr. Xu, I'm very interested in old books, can you read these books?"

"Huh?"

"I'm sorry, Mr. Xu, does it affect your work......

"It's not ...... This ......"

"It's just for a while, Mr. Xu, you can do your own thing, there's no need to accompany us here."

"This ......"

"I'm really embarrassed, Mr. Xu, look at this ......"

"Well, it's nothing...... They are all worthless old books, and there are no ancient books or unique books. ”

"I'm just a personal interest."

"Oh...... All right...... I'm just outside, and you can call me anything. ”

"Okay, thank you so much."

"Thank you, Mr. Xu."

"No, no, no."

……

"That...... Isn't it ......"

"Well, there's something here, something that used to have left traces."
