After the cold wave passed through Binhai, the temperature dropped directly to minus 5 degrees at 6 o'clock in the morning.
This is a rare cold weather for Binhai.
After getting up, Yu Zhiming came to the living room and felt a warmth wrapping around him.
Unlike the bedroom, the oil heater placed in the living room is left on all night.
When the Youting electric heater is working, there is also a slight noise. At least, Yu Zhiming can hear it, and it is quite clear.
Therefore, before going to bed, he always turns off the electric heater in the bedroom.
Yu Zhiming came directly to the sofa bed and noticed that Qing Ning's eyelashes moved slightly, and his breathing also changed.
He knew that this guy was pretending to sleep.
Yu Zhiming did not reveal it and took her temperature with the palm of his hand.
The test results were good, and Qing Ning’s body temperature finally returned to normal.
"The body temperature is normal!"
"Qing Ning, don't pretend to be asleep. Get up quickly. After I finish washing, we can do aerobics together."
"And fourth sister, don't stay in bed."
Yu Zhiming warned the fourth sister by the way, pinched Qing Ning's cheek, and went to the bathroom to take a shower and wash up.
Ten minutes later, Yu Zhiming came out of the bathroom and saw Qing Ning wrapped in a quilt and squatting on the sofa bed.
"Zhi Ming, my body is still a little weak and uncomfortable. I still need to rest and cannot exercise."
The little guy defended himself delicately, then took out his cell phone and waved it at Yu Zhiming.
She chuckled and said: "Tell you a funny thing."
"A distant cousin of mine in my hometown sent a request for help to the family early in the morning."
"Ask how to tell the size of twins."
"What do you mean?" Yu Zhiming was a little confused.
Gu Qingning chuckled and said: "This guy has a pair of twin sons, both three months old."
"Last night, I gave my two sons a bath."
"He and his wife were confused for a while, and they didn't know who was the boss and who was the second child."
Yu Xiangwan, who was cleaning up the foldable bed, interrupted and said with a smile: "Why do you need help for something like this? Since you can't tell the difference, just point to someone and call it the boss."
"The child is so young, only three months old, and has no memory of this at all. It doesn't matter who is the eldest child."
Gu Qingning said seriously: "Sister, this kind of thing is not something to be done casually."
"One is one, two is two!"
"Just because of the difference in ranking between the eldest and the second child, their personalities will be quite different when they grow up."
"We should strictly follow the birth order determined by nature to determine their age."
"Instead of us specifying it arbitrarily, it would be too unfair to the boss."
Gu Qingning gave another example: "If we were to leave it in ancient times, the gap in status and treatment between the eldest son and the second son would not be based on Taoism."
"There is only one heir to the throne and family."
"The identification of the boss and the second child must not be ambiguous."
Yu Xiangwan was somewhat dissatisfied with her words, but did not continue to argue with Gu Qingning about the matter.
Gu Qingning shook her phone again and continued: "My cousin and his wife basically stayed up all night, just thinking of various ways to determine who is the boss."
"But now that they have made the distinction, they are at a loss. They are becoming more and more uncertain and not sure."
Yu Zhiming said happily: "It seems that this couple does not take good care of their children."
"After raising them for three months, you still can't tell who is who at a glance. This is very unqualified."
Gu Qingning rolled her eyes at him and said, "Zhi Ming, don't say sarcastic words, just tell me if there is anything you can do?"
Yu Zhiming shook his head and said: "As biological parents, they can't even identify them, and there is nothing others can do."
"Now that there is no successor to the throne, why not just follow what my sister said just now and make one child the eldest son."
"How can I say it, there is a 50% accuracy rate."
Yu Xiangwan spoke again: "It's just that times have changed, and it's not good to take some things too seriously."
"I know that for many twins born by caesarean section, it is not the doctor who decides who comes out first."
Yu Zhiming echoed: "That's true."
"When performing a caesarean section on twins, the doctor puts his hand in and takes out whichever one is more convenient first."
He added: "I do know that if you are pregnant with twins, some parents will specifically tell the doctor to let the sister come out first, or let the brother come out first."
Gu Qingning pointed at the Yu siblings and asked, "Is your relationship as a sibling specially arranged by your parents?"
Yu Zhiming reached out and flicked this guy on the forehead.
"My mother gave birth naturally."
He also popularized science: "Qing Ning, let me tell you, if it is fraternal twins, the first fertilized egg will usually implant above the uterus, and the second fertilized egg will implant below the uterus."
"If it's a normal delivery, the second child will come out first."
Gu Qingning hummed and said: "This is a question of the formulation and implementation of standards. In our country, the standard that is implemented is that the mother carries the baby first."
Yu Zhiming reached out and rubbed Qing Ning’s head.
He suddenly thought of something and said, "Qing Ning, your cousin has recorded videos of children before, right?"
"If their cries, laughter and other sounds are recorded, I can distinguish them based on the sounds."
Gu Qingning jumped up and said: "Oh, I was so confused for a moment that I forgot that you have a super high ability to distinguish sounds."
"I'll tell my cousin right now..."
After Yu Zhiming finished her aerobics, Gu Qingning also communicated with her distant cousin and sister-in-law.
The four of them set up a video connection in the bedroom.
An unshaven man with a slicked back hair and red eyes, and a woman with a high ponytail, appeared in the online video.
"Dr. Yu, Qing Ning, hello!"
"I'm sorry to trouble you so early in the morning."
The man with the big back said politely, picked up the phone and said: "This is a video recorded when my eldest was born. He cried loudly and was full of energy."
After speaking, the loud cry of the baby echoed clearly in the bedroom through the connected mobile phone.

Yu Zhiming felt a headache reflexively.
To him, the cry of a child is no less than a weapon of mass destruction.
After the child stopped crying, he urged: "You can make a child cry."
After the camera shook for a while, Yu Zhiming saw two babies lying side by side on the bed, sleeping soundly on the connected mobile phone screen.
The child looks white and clean, very cute.
"So beautiful." Qing Ning praised from the bottom of her heart.
The next moment, Yu Zhiming heard the couple's thin conversation coming from the mobile phone.
"You come!"
"It's you who come!"
"I'm your biological father, I can't bear to let you go!"
"I'm not a stepmother either, so why should I give up?"
"What about guessing?"
"Okay! One round will determine the outcome!"
After two rounds of scissors and hammering, Yu Zhiming saw a big hand twisting the face of the child on the left.
The next moment, the loud crying sounded again.
Yu Zhiming endured his headache and shouted: "Okay, okay, this is the second child, not the boss!"
As soon as he finished speaking, another cry sounded.
Apparently, another child was woken up.
Hearing the child's cry, Yu Zhiming ignored his headache and asked loudly: "Are you sure that what was played before was the cry of your boss?"
The screen shook again, and at the same time, the cries of the two children became much quieter.
Obviously, cell phones should be kept away from children's bedrooms.
Immediately afterwards, the head of the man with a big back appeared on the screen.
"I'm sure it's the cry recorded when my eldest son was born."
"Doctor Yu, is there something wrong?"
Yu Zhiming said slowly: "I can confirm that the cry just now is not comparable to the cry of your two children."
He then explained: "Either the crying that was recorded before was recorded incorrectly."
"Either it is that your eldest son's vocal organ has undergone relatively large physiological changes."
A loud voice came out of the phone, "Doctor Yu, what do you mean..."
"Either my two sons were hugged wrongly, or my eldest son has a disease in his vocal organ?"
Yu Zhiming replied cautiously: "I just made an analysis and inference based on the inconsistency of this sound, which may not be accurate."
The man with a big back on the screen said with a serious face: "Dr. Yu, I have heard about your ability for a long time."
"Your inference will most likely not be wrong."
"However, it is impossible to hold the wrong son."
The man with the big back said with certainty: "We are staying at the best maternity center in our local area."
"After the two children were born, they were never separated from anyone. There is no possibility of miscarrying them."
"Is that a disease?"
"Doctor Yu, what kind of disease could it be?"
Yu Zhiming replied softly: "There are many possibilities, but it is difficult for me to judge accurately based on this sound alone."
"Take your child to the hospital for a checkup..."
Yu Zhiming ended the video connection, and Gu Qingning's voice rang in his ears.
"Zhi Ming, was it true that the child was not secretly exchanged?"
Yu Zhiming reached out and tapped the tip of this guy's nose and said: "This possibility is extremely small."
"As long as it is a regular hospital, the management of newborns is quite strict, and the possibility of miscarrying or secretly changing babies is very slim."
"There is a high probability that there are physiological changes in the vocal organs."
Yu Zhiming criticized himself again: "Of course, I don't rule out the possibility that I heard it wrong."
Gu Qingning defended confidently: "Whether it's disease diagnosis or voice recognition, you haven't made any mistakes yet."
"This time, you will be no exception."
She prayed again: "I hope it's just a small lesion. He's only three months old. I can't let the child suffer too much..."
During lunch time, Yu Zhiming received a call from Qing Ning.
"Zhi Ming, it's a disease of the vocal organ."
"My cousin said that an abnormal bulge was found in the child's throat."
"The specific situation needs further inspection."
