The huge body of the Boeing 737 slowly stopped on the wide runway of Pudong Airport. Shen Yanran looked out of the porthole, different from the gloom when she left New York yesterday, the sky in Shanghai at this time was cloudy. Shen Yanran smiled and slowly walked out of the cabin, and the passenger lady at the hatch smiled and said goodbye to her. When she left the station, she was required to fill out the contact form for the immigration personnel on the plane. Customs security carefully checked each document, when he picked up the U.S. passport in his hand and compared it to the list she filled out, looked at the Columbia University – College of Physicians and Surgeons (New York) Columbia University Doctor of Biomedical Sciences, looked at the woman in front of him, and lost his mind for a while.

Shen Yanran walked out of the waiting hall and took a deep breath, an indescribable emotion filled her heart.

Sixteen years later, she finally set foot on this land again.

Walking out of the airport, she waved to stop a car. The driver's eldest brother was very enthusiastic, "Miss is from Suzhou, right?" Yan Ran looked at this uncle in surprise, the uncle had long been used to it, and continued, "A look like Miss can only be found in the Zhongxiu Land of Jiangnan Water Town" Yan Ran smiled when she heard this. "Where is Miss?" After the driver's uncle smiled and helped her move her luggage, he asked softly, and Yanran showed him the address in her hand, which she had kept silently in her heart for sixteen years.

The car was speeding down the open road, and everything outside the window was so pleasantly surprised.

When I left home in my childhood, my memories have been blurred, the gloomy sky, the smoky rice fields, the gray and sparse houses, and the pain that has been hidden for so many years and can never be erased.

Uncle was talkative all the way, although the Mandarin spoken in a slight dialect sometimes made it a little difficult for Yan Ran to adapt for a while, but Yan Ran still listened with a smile, all this outside the window was so novel. She asked some questions stupidly, and the uncle said tirelessly. More than an hour away, quietly drifting by in conversation and laughter.

Standing at the mouth of this alley, Yanran had a trance. Time seems to have returned to childhood, the green tile eaves, the clusters of spring by the wall, jasmine, Yueji, and the creeper that occupies a wall.

"Yanran" seemed to hear the familiar call in his ears again, and the figure hidden deep in his heart was blurred in front of him. "Dad, Mom, I'm back", the pain in my heart surged up again. She was accustomed to taking a deep breath, and the homesickness was even more timid, and a mixed feeling of anticipation and fear firmly grasped her.

It has changed too much, and with the remaining pictures in my memory, I am groping and searching.

The wind blew gently, the light beige silk scarf was gently raised in the sun, and the sound of broken footsteps stepped on the bluestone path, step by step, towards the familiar courtyard gate.

No. 8 Yaji Lane. His hands were trembling slightly, although he had been on the phone a few days ago, but at this moment Yanran's heart was still worried.

The doorbell rang, and it was a familiar face that opened the door, although it had been so long, the love on the wrinkled face was still there, and the warm eyes were ..... Yanran rushed over, hugged the person in front of her tightly in her arms, and whispered "Grace Milk" in her ears. The person in front of him had already burst into tears, "Little Miss is back, my Yanran is back."

Walking into the house, everything seems to have not changed, the white-walled tile house along the road in the front yard of the three-bay room, the furnishings are the same as before, the sandalwood fragrance in the Buddhist shrine, the four immortal tables have long been unable to see the original color, but the appearance of the two immortals is still vaguely arguable. In the kitchen, a few new appliances have been added that were not there before, but the walls still retain all kinds of strange crows that she drew with her pen when she was a child.

Grandma's room is still in the innermost room, and everything is still the same as before.

"Grandma", "Little Miss", "Grandma, don't call me Little Miss, let's call me Yanran" "Okay, good".

"Yanran, come on, your mother's house in the back garden has been renovated, do you like it?" Grandma took Yanran's hand, pushed the door and walked into the backyard. After the door opened, Yanran only felt that her eyes were bright, a square yard, the entrance was a curved bluestone path, and at the interval of the board, there were pebbles to put together various patterns, and a murmur of water passed away quietly. Across the water, there are patchwork of flowers among the stone slabs on the ground. A vermilion wooden covered bridge flies over the flowing water. The ginkgo tree was still there, and its hands were no longer together.

The two-story Supai building with three bays in the front, the wooden doors and windows are perfectly kneaded with the pale cyan glass. Dai wall is connected with gray eaves, green tiles into the delphinium, the ridge and corner are linked to the Pleiades, and the charm is stored in the south of the Yangtze River. Although she had already received the decoration drawings of the house on the Internet, standing here today still deeply moved her.

A YEAR AGO, HER MENTOR IN THE UNITED STATES, ALEX, TOLD HER THAT THERE WAS A COLLABORATIVE PROGRAM IN HER HOMETOWN THAT SHE COULD RETURN TO FOR A YEAR. SHE TOLD ALEX THAT SHE DIDN'T WANT TO STAY IN THE COLLEGE'S ARRANGED HOTEL, AND SHE WANTED TO GO BACK TO HER HOME, BUT SHE HADN'T BEEN BACK FOR SO MANY YEARS, AND THE DOMESTIC PERSONNEL WERE TOO FAR AWAY FROM HER. ALEX ARRANGED FOR SOMEONE TO HELP HER DECORATE HER HOUSE. I remember at that time, the designer asked her online what she wanted? All she said was "so I can still recognize it".

Yes, he did, everything changed, but everything didn't seem to change. This window, a grid, a flower, a tree, a wall and an eaves, she can still find a fit in her memory.

Grandma took her hand, walked into the house, pushed open a room with carved north windows, there was a thick smell of agarwood incense, Yanran walked in gently, and there were two black and white photos on a long table of purple and red sandalwood.

Yanran quietly leaned over, wiped the photo frame, gently stroked the smiling face in the photo with her fingers, and gently held the photo frame in her arms, "Dad, Mom, Yan'er is back"

Grandma closed the door with her hands lightly, and Yanran in the room held the photo, tightly, her face rubbing the frame. Kneeling on the puff mat, tears quietly slipped down.

After eating the side dishes roasted by En's milk, Yanran sat on the swing under the tree, the autumn insects chirped low, the breeze blew, and time seemed to return to childhood......

The next day, Yanran came to the hospital to report for duty. She returned to China with an academic seminar project, and the hospital had been waiting for her for a long time. The new project she brought this time is great news for the city's medical community.

The appearance of the hospital in her childhood memories made Yan Ran a little incredulous about the huge complex in front of her. Walking into the emergency building of this hospital, which looked inferior to foreign countries, Shen Yanran asked a nurse at the front desk, and when the nurse heard about her intention, she immediately called the hospital office. Soon, the elevator opened, and a talented young man in a white coat and silver glasses walked towards her. "Hello, are you Miss Shen?" Yes, I'm Shen Yanran" "Hello, the smile is deeper, my name is Song Peng". Welcome to our hospital.

"Thank you, Yan Ran glanced over and saw that the sign on his chest reads - Shen Peng, Deputy Chief Physician of the Department of Neurosurgery

Before returning to China, Yanran also had a general understanding of the hospitals in China, this person was young, heroic and tall, and he looked less than thirty years old. It seems that it is not easy to be the deputy director at such a young age.

On the elevator, Yan Ran was taken directly to an open office on the sixth floor, where a man in his forties stood up, and when he saw Yan Ran, he lost his mind for a while.

"Hello, my name is Shen Yanran." Yanran stretched out her hand, "Oh, hello, I'm Liu Jian, and I'm the vice president of this hospital. ”

When Yan Ran got to know her, Song Peng took her to a window-facing office in the south area on the sixth floor, and Yan Ran could clearly see that the office had been carefully sorted out, and the green potted plants along the window were verdant. Interior office supplies are readily available, the milky white leather sofa at the entrance shines gorgeously in the sun, and a few lilies in a glass vase on the coffee table in front are in full bloom.

"This is your office, and if you think you need anything, just tell me." "Thank you, it's good." Yanran smiled. Song Peng smiled, his eyes flashing.

It was already dark, and Yanran walked out of the hospital gate. Song Peng had been waiting for a long time. As soon as I saw that shadow, I hurriedly greeted it. "How about it, tired, on the first day today, you don't have to work so hard, there is time later". "Thanks, I just want to get the work at hand down as soon as possible, why are you here?" "I, I think you've just come back from abroad, and you're not familiar with the environment here, so I'll be your guide, how are you, are you hungry? Can I have dinner with the light? I would like to thank my international friends for their help."

When Yanran heard this, she couldn't help but laugh, but looking at the face full of sincerity in front of her, she nodded.

Song Peng drove the car and introduced the scenery and allusions along the road to Yanran all the way. The car entered a garden-style house. This restaurant with a strong Jiangnan flavor is very much liked by Yanran. The dinner was very pleasant under the active guidance of a caring man.

After the meal, the two walked out slowly "Yanran", and Song Peng had already pulled the title from Miss Shen to Yanran directly in one meal. "Tomorrow, the leaders of the hospital will hold a banquet, which is specially for you, not only from our hospital, but also several leaders from other hospitals will participate." "Ah, how come I don't know?" Yanran is also grateful to the young man in front of her, "I said that I wanted to surprise you, I think the main thing is that the project you brought back this time has really helped us a lot, this is the thirst for talent."

Yan Ran listened to it and was noncommittal.

At the reception banquet the next day, as Song Peng said, all the leaders of the medical community in the city came, and Yanran couldn't help but feel apprehensive in her heart, and she also felt the weight of the burden on her body. It can be seen from the words that the country is so urgent about this project. MENTOR ALEX'S ADVICE BEFORE LEAVING WAS IN MY EARS. "Susan, I understand your urgency to go home, you have been in the United States for sixteen years, and only ten years in China, in my heart, I have long thought that you are an American. You know, you are one of my proudest students, and your intelligence and hard work have brought you where you are today. As you know, it is very difficult for you to return to China this time, and for a talent like you, no matter where you are, it will be highly regarded. In particular, many of the research projects you are exposed to are confidential. So you're going to China this time, and I hope you understand that. ”

"Medicine knows no borders," she muttered as she thought about it, and sighed deeply in her heart.

In the following days, Yanran shuttled between the laboratory, the office, and the library. And Song Peng is like a primary school student. Firmly occupy the position of assistant, driver, and flower messenger
