Shen Lin had already begun to lean towards Yao Bin's judgment in his heart, but he was still habitually unconvinced: "This is just an aisle, big guy, your old man is used to the physical fitness of world-class athletes, but with a small body like me, my lung capacity can't enjoy the poison of these details, right?" ”

"No matter how small the details, they are also part of the sleeping environment," Yao Bin said, "Since you are in a hurry, let's take a look at the more intuitive factors first." ”

After speaking, Yao Bin instructed Shen Lin to return to the room.

"According to my observation in the past 62 days, you can basically fall asleep after 11 o'clock every night, and you are especially prone to waking up around 6 o'clock in the morning, do you feel it yourself?"

"Uh......" Shen Lin scratched his head and thought about it carefully: "It seems that this is really the case." ”

"Do you know why?"

"Huh?" Shen Lin shook his head.

"Open the window." Yao Bin instructed.

Shen Lin opened the window: "And then?" ”

"Sit well, don't move, listen carefully to the movement outside."

Shen Lin sat still.

Soon, Shen Lin heard a faint, intermittent, and completely irregular "clang", "clang", "clang", "clang", ......

"Ah, I remember!" Shen Lin remembered: "The road two streets away has been under construction recently, and there is a gap that has not been completed, and the municipal government has laid an iron plate!" It's the sound of a car driving over an iron plate! ”

"Yes." Yao Bin confirmed.

"That's not right," Shen Lin frowned slightly, "It's so far away, this voice is already very soft, and I closed the window again, it shouldn't have any effect, right?" ”

"It's not the sound that affects you." Yao Bin first affirmed Shen Lin's thoughts, and then continued: "At this distance, the influence factor of the sound wave itself is already very small, but the vibration generated by the car driving over the iron plate, as well as the frequency of the sound wave itself, will still produce a resonance that is not obvious enough when transmitted to the building of your apartment, but the body can still feel it in a relaxed state. One thing to note is that this is a rather irregular resonance. Before 11 p.m. every day, and after 6 a.m. every day, it is the busier time of the street, and during this time, the quality of sleep is bound to not be very good when you bear this resonance. ”

"I see!" Shen Lin suddenly realized: "No wonder I always feel like I can't get out of bed during this time." ”

"Actually, it's not that you can't get out of bed," Yao Bin's tone was very serious: "According to my observation in the past 62 days, when you first woke up during this time, you often had a slight headache, weakness in your limbs, and an irregular heartbeat, which is not tiredness, but a manifestation of mild neurasthenia." ”

"Isn't it?" Shen Lin muttered: "Don't it be so serious, I just rented a house casually, how can I rent a nervous breakdown......"

"The problem with the windows is not only this," Yao Bin ignored Shen Lin's feelings, and continued: "A good sleep should be to breathe fresh air, but you usually can't open the windows at all, one reason for the hot temperature in summer, and the noise of cars coming and going outside the window is another reason...... Well, now it's a little later, the garbage truck of the sanitation department is coming, and if you accidentally float in to smell something, it doesn't matter if you can sleep or not, and whether you can eat in the next three days is a problem. ”

"Uh......" This is all personal experience since renting, Shen Lin was speechless.

Before Shen Lin could feel it, Yao Bin had already said quickly:

"It's true that your room has a north-facing layout, but it's 32 degrees north-facing south, and there is strong light at 5 o'clock in the morning during daylight saving time."

"The core purpose of the curtains provided by the apartment is to make the tenants feel pleasing to the eye when they visit, not a blackout material, and there is no sound insulation."

"The bed board is fiber plywood, the thickness is quite uniform, not so that it is embarrassing, but the specific heat capacity is too low, cold and hot in summer; If the intensity is too low, it is easy to make abnormal noise. ”

"The floor drains in the washrooms and toilets are not properly designed...... Well, maybe there is a problem with the design and installation of the sewer pipes, the air is humid, and it affects the smooth breathing. ”

“……”

Yao Bin counted them one by one, and each one left a gap for Shen Lin to think.

The result of thinking is very depressing.

Shen Lin had great doubts about his vision: Damn! Rental agents really don't have a good thing, there are so many routines!

Yao Bin's narrative is not over yet:

"The sheets are made of polyester, which does not keep warm or dissipate heat, and the only advantage is that it is inexpensive."

"The blanket is synthetic of crushed velvet, which is sealed and airtight, and the best use is for curing meat."

"The pillow is a down pillow and the material is ok, but this one is not suitable for summer use. INTERVIEWER Also, this pillow was issued by the school when I was in college, and I haven't washed it once until now. - You can guess how many bacteria and stains it has accumulated over the years to thank you for your kindness. ”

"Mattresses are ......"

"Pillowcase is ......"

"Pajamas are ......"

Yao Bin still counted them one by one, and there was still a gap for thinking in the middle of each one.

This time, Shen Lin could no longer push the responsibility out of the rental agency.

Fortunately, Shen Lin still has room for flexibility: Damn! A treasure merchant is too much of a thing, and all kinds of broken things are pushed out!

Shen Lin's anger reflected his subconscious resistance, and this young man was unwilling to accept it: he basically couldn't understand most of what Yao Bin had just narrated......

What Shen Lin is even more reluctant to admit is that he has lived until now, and he has lived for more than 20 years, but he has not even touched the edge of the knowledge of sleeping......

"It's just a sleep," Shen Lin couldn't help but complain: "Do you want to be so particular?" ”

"It's just a good night's sleep," Yao Bin snorted: "In a narrow sense, 24 hours a day, 8 hours a day, one-third of a person's life is spent sleeping." Compared with food, entertainment, travel tools, personal vanity, and ideal pursuits, the enjoyment of one-third of sleep is already the most cost-effective investment, do you think you don't need to pay attention to it? ”

"But ......" However, Shen Lin also had a hard time: "Boss, I do have limited ability and lack of experience, but since your old man has already instructed, bed sheets, mattresses, blankets, pillows, pillowcases...... Well, and the pajamas, which I can change right away. - As long as my funds can support ......"

As he spoke, touching the cash that had just come back in his pocket, Shen Lin smiled bitterly: "However, the software is good, and I will definitely work hard!" But in terms of hardware...... I've seen better houses too. That's right, the lighting is a little better, and the environment is quieter, but to meet what your old man just said about resonance, specific heat capacity, floor drain design or something...... I'm afraid it's not realistic, right? ”

"Why isn't it realistic?" Yao Bin chuckled: "For a house suitable for living, these are just basic requirements. ”

"The basic requirements ......" Shen Lin smiled bitterly and shook his head: "After graduation, I have been to three cities, rented a house five or six times, and seen dozens of ...... It may be that there are more than 100 houses, and I have never seen a place that meets so many 'basic requirements' of your old people. ”

"Really?" I don't know if it's an illusion, from Yao Bin's words, Shen Lin seems to hear a vague sympathy: "It's okay, you'll see it later." ”
