Applause erupted around them, and Zhou Jianguo and the others hurriedly gathered around to ask about first aid techniques.
Lin Li took the handkerchief handed to her by Lin Laosan, wiped her hands, and pointed to the spot where the child had just been, explaining, "This is the Heimlich maneuver. Mastering the golden four minutes can give you a chance to save a life..."
"The Heimlich maneuver? Girl, can you save everyone?"
A man with gray hair, wearing black-rimmed glasses and a dark gray Zhongshan suit stepped forward, his eyes shining brightly behind his lenses.
"Who are you?"
"Hello! I'm Professor Li from the Department of Medicine at B University. I happened to be at Tsinghua University today to chat with an old colleague when I witnessed this scene..."
"Hello, Professor Li!"
"Could you teach this life-saving method to everyone at B University? As you know, there are only four golden minutes after someone gets stuck in a foreign object. If you miss that, the consequences are unimaginable!"
When Lin Li heard Professor Li say this, she also thought of how many children in her previous life lost their lives because they didn't receive timely first aid.
That's why this first aid method was widely publicized at the time.
"Okay! I can now teach everyone this life-saving method in a critical moment."
As she spoke, she handed the handkerchief in her hand to Lin Laosan and tucked the stray hairs that had fallen out during the rescue behind her ear.
"First, remember the mnemonic—scissors, rock, paper."
She brought her left index and middle fingers together like scissors, pointing two finger-widths above her navel. "The scissors shouldn't be too low, otherwise they'll injure the internal organs; nor should they be too high, avoiding the xiphoid process."
As he spoke, he clenched his right fist, with the knuckles aligned with the tip of his left index finger, "The stone is like this, with your thumb pressing against your abdomen and your palm facing inward."
Finally, her right hand was quickly wrapped by her left hand. "Tighten the cloth and thrust your arms backward and upward with force."
The professors and students watching began to imitate her movements. Lin Li walked up to a girl and gently adjusted the position of her arm.
"The power comes from your waist, not your arms. Imagine you're using this movement to 'squeeze' something out of your throat."
She turned around, picked up a dead branch from the roadside, drew the outline of a human body on the ground, and marked the vital points. "The technique is different for children and adults. For children under three years old, you should use two fingers to press and apply more gentle pressure."
Suddenly, a question came from the crowd: "What if you have to save yourself?"
Lin Li walked to a stone bench and demonstrated: "You can use the back of the chair to press your abdomen against a hard object and squeeze it inward and upward with force."
She suddenly coughed violently, her brows furrowed and her face flushed. Just as everyone looked on with concern, she returned to normal: "This is how a simulated suffocating person behaves. If you find that the person is unable to speak or cough, you must provide immediate assistance."
After hearing her words, everyone nodded heavily.
Professor Li had already taken out paper and pen and wrote down every word she said.
"Remember, the golden rescue time is only four minutes."
She bent down and picked up the peanut that had almost caused a tragedy. "Foreign object obstruction can happen at any time. The more you learn, the more lives you can save."
After noting down the last smile, Professor Li put the pen and paper into his pocket, pushed up his glasses that had fallen off his nose, walked forward, took Lin Li's hand, and shook it repeatedly.
"Thank you, thank you, young lady, your method is very useful!"
"You're welcome!"
Lin Li looked at Professor Li's face and smiled as well.
"Young lady, you're a student at Tsinghua University. Which department are you in? Would you be interested in attending classes at Peking University?"
Professor Li's eyes lit up, and he immediately thought of recruiting Lin Li to the medical department of Peking University. Such an outstanding medical talent was being wasted at Tsinghua University.
"Cough cough cough!" Lin Li coughed a few times uncomfortably, then pointed at Lin Laosan, "I'm not a student at Tsinghua University, I'm a mother of a Tsinghua University student, and I'm here with my son to register today."
Professor Li looked at Lin Li's youthful face, then glanced at Lin Laosan in disbelief, "He's your son?"
"A genuine biological son!"
After hearing Lin Li's introduction, Lin Laosan also straightened his chest.
"No way, you don't look like you have a son this big!"
"Maybe it's because I take good care of myself!"
Professor Li's eyes lit up even more after hearing Lin Li's words. He was determined to win over such a talented medical professional and bring her to teach at B University.
"Then, Aunt..." For a moment, Professor Li didn't know how to address Lin Li.
"I'm 45 years old this year!"
"Then I'm older than you, so I'll call you 'little sister'!" Professor Li breathed a sigh of relief after hearing Lin Li's words.
"Hey girl, would you be interested in auditing classes at B University's medical school?"
"Of course I'm interested!" Lin Li immediately agreed to Professor Li's invitation.
B University's medical school is a prestigious institution among medical schools in later generations. Of course, she would immediately agree to be an auditor and systematically learn medical knowledge.
"Okay! Then come to the medical department of B University tomorrow. This is my name and phone number."
As Professor Li spoke, he took out a pen and paper, wrote down his name, address, and office phone number, and handed it to Lin Li.
We are very much looking forward to your joining us!
"Thank you, Professor Li."
Lin Li carefully put the note into her pocket, and after finding out the class time, she decided to go on time.
After the crowd gradually dispersed, Lin Li prepared to leave Tsinghua University. Lin Laosan and the others still had to go to their department to report that evening.
"Mom, I'll go back with you. I'll go cancel the lease!"
"Alright!"
Starting tonight, Lin Laosan will be staying in the dormitory; the guesthouse room can be cancelled.
The mother and son walked back to the guesthouse. After returning to their room, Lin Laosan took his watch out of his pocket.
"Mom, please keep this watch for now. I'll just wear my old one!"
Lin Li took the watch and looked at him in surprise.
"This watch is too eye-catching; I don't need it right now!"
Lin Laosan thought about how attentive the receptionist had been to him because of his watch, and how Xiao Wang at the sales office stared at his watch with shining eyes.
The people in Beijing have very sharp eyes; he didn't want to become that special person at school.
When Lin Li heard what Lin Laosan said, she also thought about the attention the two of them had received for their clothing these past few days, and nodded in agreement.
"Okay, I'll keep this watch for now, and I'll give it back to you after you graduate!"
"good!"
After watching Lin Li put the watch in her spatial storage, Lin Laosan breathed a long sigh of relief.
"Mom, will you continue to stay at the guesthouse for the time being?"
Lin Li is going to B University's medical school as an auditor tomorrow, and it's too inconvenient for her to stay in the guesthouse all the time.
However, Shirako's house cannot be occupied for the time being.
She inquired about the house in Fangzhuang with Xiao Wang, the real estate consultant at Baizifang, and was told that construction had not yet started and the house would not be delivered for several years.
