There are usually dedicated elevator attendants in hospital elevators.

When elevators first appeared, many buildings had elevator operators. Now, only hospitals have them. They mainly serve people who come to hospitals, as many people are not convenient to press the elevator button.

But this hospital has so few people, and it still needs elevator operators? There are four elevators here. If each elevator is equipped with an elevator operator, at least eight people should be hired, right?

This luxurious configuration doesn't quite match up with the low-profile male guide outside...

Maybe the second scenario Liu Shuyuan mentioned is true? It seems that only this one reason can explain it - the hospital doesn't expect to make money from medical treatment at all, but just wants to secretly promote it to attract as many people as possible so that it won't be too deserted.

Liu Shuyuan had no idea that Bai Song had so much in mind, so he entered the stairs and directly pressed the button for the top floor, the 13th floor.

"Eh?" The female elevator attendant took Liu Shuyuan's hand away unhappily. "Which floor are you going to? Tell me and I'll press the button."

"The top floor." Liu Shuyuan said.

"Okay." The female elevator attendant pressed 13 impatiently, then held the elevator door with her hands, as if she had to wait for another wave of passengers before leaving.

Is there such an operation? Bai Song didn't know what to say, but soon, two old men came in.

"13th floor." The two old men could tell it was not their first time here, so they told the elevator operator the floor directly.

The elevator ran very stably, and it was obvious that the hospital's infrastructure was good. During the time in the elevator, Bai Song carefully observed that the buttons for floors 1-6 were used more frequently, and the top floor was 13. Floors 6 to 12 were for inpatients, but it was estimated that one floor on the 6th floor was enough to accommodate all the patients.

Soon, they reached the 13th floor and the two old men took out table tennis rackets from their bags.

Gym? Bai Song and Liu Shuyuan didn't understand and followed the two grandfathers.

The 13th floor is a high-care ward, which is also the configuration of many hospital inpatient buildings. The top floor has the best facilities, and this hospital is no exception. Bai Song was a little confused. With so few people in this hospital, is there anyone willing to spend a lot of money to live in a high-care ward?

Following the footsteps of the two old grandfathers, Bai Song discovered a clue.

There are two large rooms here, which have been converted into an activity center for the elderly, and it seems that they are open to the public free of charge.

The activity center here has two ping-pong tables, some chess and other simple sports facilities in one room, and a library where six or seven elderly people are reading.

Perhaps these rooms were intended to be used as intensive care wards when they were first built, so the interior decoration is very fine, the sofas and chairs inside are also exquisitely crafted, and even the two ping-pong tables look very professional.

When the two old men arrived, there were people playing on the two ping-pong tables, and there were seven or eight people watching. However, the two old men should be regular customers and some friends. They greeted everyone and started playing themselves after a while.

The nearest residential area is three kilometers away. Logically, it would not attract people here at all. However, with a place like this, especially one that is free, it is natural that it can attract people.

After watching table tennis for a while, the two went to the corridor and continued walking around.

Each floor is very large, covering an area of ​​2,000 square meters. Except for these two activity rooms, other rooms are mostly closed. Those that are open are basically filled with some hospital sundries, mainly tables, chairs and benches.

After taking a look around and finding nothing special, the two went to the library.

This is a very user-friendly mini-library. Perhaps because there are many elderly people here, there are public AEDs, blood pressure monitors, nitroglycerin, reading glasses, etc., and there is no one here to serve as an administrator. (Note 1)

Is this a real welfare hospital? The two entered the library, which was quite large, with tables and chairs. Bai Song found a familiar book on the bookshelf and started reading.

Before I knew it, more than ten minutes had passed.

"Hey, Captain Bai, how long do you plan to stay here?" Liu Shuyuan turned around a few times and found that Bai Song was becoming more and more fascinated, so he asked in a low voice in Bai Song's ear.

"Read this book." Bai Song handed the book to Liu Shuyuan and also lowered his voice.

Liu Shuyuan took the book and found it was a novel. He looked at it carefully and found nothing special. He returned it to Bai Song with a puzzled look on his face: "I don't see any problem."

"Take a look at the last page of the book." Bai Song handed it to Liu Shuyuan again.

"Xu Fang...Bai...Bai Song?" Liu Shuyuan was stunned when he saw the author's name: "Is it the same name as yours?"

Bai Song shook his head gently.

Liu Shuyuan was stunned. He read the book's introduction, flipped through the book, and returned it to Bai Song again. "After talking for so long, it seems like you are showing off to me that you wrote a book?"

Publishing a book is not a difficult thing, especially now that the entry level of publishing is getting lower and lower. With a few thousand yuan, you can publish your own works. Bai Song participated in writing this book, and Liu Shuyuan thought it was very impressive, but there was no need to be so pretentious...

"I didn't let you see the author. The publication date was three months ago." Bai Song said in a voice that only Liu Shuyuan could hear: "The library here does not buy used books, but purchases new books regularly."

Only then did Liu Shuyuan realize what Bai Song wanted to say.

When Professor Tang was selling those old books, although they were old, they were basically new books that no one had touched, they were just stored for a long time. Such books are very, very cheap, and basically some public welfare libraries have such books, the price is very low, and they are weighed by kilogram.

But buying new books would cost more than ten times as much?

This place is really expensive, isn't it?

"I guess the hospital bought these books to offset taxes." Liu Shuyuan explained again.

Bai Song thought about it for a while, nodded, and agreed with Liu Shuyuan's statement. In these professional business practices, Bai Song was a blank slate.

The place where he was sitting was a blind spot for all surveillance cameras.

There are four surveillance cameras in this room, mainly concentrated near the door. Bai Song discovered them the first time he came in. After sitting here for a while, he also studied the nearby structure.

After putting the book back, Bai Song walked out without making any sound, and Liu Shuyuan followed closely behind him.

"Did you find any problems?" Liu Shuyuan looked around in confusion: "I don't see any problems, it looks normal."

"Yes, it looks fine." Bai Song thought for a while and asked, "But do you think this place looks a bit like an office building?"
