"I am curious about everything about this child, but I am also a little worried. He is like a quagmire. The closer you get to him, the more dangerous he becomes."

"The child's mother suffers from bipolar disorder. She will not be so nervous until she sees her child. In order to facilitate treatment, our doctors always take the child to see her, mainly to alleviate her condition."

"Children have a natural dependence on their mothers. Even though he is so young, he can already recognize his mother."

"But what I find strange is that the first word the child uttered was not 'mother' or his own name, but 'door'."

"At first I thought I had misheard, or that it was the child's unconscious voice. Maybe when the nurse picked up the child and left, he pointed with his pink little hand at the door of his mother's room, repeating the same word - door."

"He seemed to be conveying to us that he wanted to get closer to that door."

"This is what makes me most uneasy. I have questioned everyone in the hospital, and no one has ever taught him this word!"

"No one taught him, but he pronounced this word and knew its meaning. Who told him this? Is there something else in my office?"

"What happened later was even more horrifying. When the nurse holding the child and I entered Ward 3 to visit his mother, the child looked at the end of the corridor and waved his hands, as if he was greeting someone."

"I saw it clearly at the time. There was no one else in the corridor except us."

"If that were all, I wouldn't be too worried."

"But then the nurse also noticed something was wrong and asked him what he was doing? Who was he greeting?"

"The child stammered out three words at the time - He Yajun."

"The nurse didn't understand the meaning of these three words. She thought the child was just babbling. She didn't take it seriously and carried the child into the back of the corridor."

"In fact, I really wanted to stop her at that time, because He Yajun really existed. Before the third ward was built, a worker had an accident, and that person's name was He Yajun."

"Even the doctors and nurses in the hospital didn't know about this, so why did he say He Yajun's name?"

"I stood at the door of the ward and watched the nurse walk away with the child in her arms. When she walked up the stairs, the little boy waved to the empty corner next to the nurse again."

"To be honest, I've seen so many crazy people with strange diseases, and I've never been scared. But that day in the corridor, I felt fear for the first time."

"After this experience, I paid more attention to him."

The first letter ended here. The dean did not say who the letter was sent to until the very end. Chen Ge read it all and only found the three words "Dr. Chen" at the beginning of the letter.

"His last name is Chen? Could it be my father? But he runs a haunted house and the profession of doctor is far from being related!" Chen Ge was overjoyed and thought he had found the clues left by his parents. Now, it seems that he was too optimistic.

When I opened the second letter, the content was even more bizarre.

"Doctor Chen, we need to meet. Things are getting a little out of control."

"When the child just learned to crawl, he would actively look for his mother. No one in Ward 3 knew how the child left the office and ran outside Ward 3 on his own."

"Other nurses and doctors have also noticed something wrong with this child. He rarely cries and always smiles at certain places. He becomes happier as the night goes on. He doesn't behave like a child at all."

"He has a strong learning ability and speaks fluently. He can say each word accurately, but the things he says always make people feel scared."

"Maybe the world in a child's eyes is different from ours. He calls patients who take sedatives and sleeping pills toys, and looks at them as if they were dead objects."

"He would shake his fist and clap his hands at the patient who had lost his mind, facing the patient but staring at the patient's shoulder as if there was something on the patient's shoulder."

"The most puzzling thing is that he likes to run outside Ward 3 and not go in. He just stares at the door and can stare at it alone for an entire afternoon."

"Some doctors and nurses suggested that I take the child away and give him to a welfare institution to raise. They were also frightened by the child."

"Sending the child away may have an impact on the mother's treatment. It took us almost a year to stabilize his mother's disease. We can't give up halfway."

"I rejected the doctor's advice. A few months later, the police received good news. They used the fake license plate car as a clue and found the biological father of the child in the south."

"At this time, the child's mother's condition has basically stabilized. We have entrusted a lawyer to sue the child's father in court, requiring him to bear the expenses of hospitalization and treatment, and also requiring him to give the child's mother a legitimate status."

"The lawsuit was won, and the father's attitude changed drastically, whether out of fear of going to jail or remorse."

"Everything is developing in a positive direction. The child's mother is gradually recovering from the illness. This young mother appears to be exceptionally strong in front of her child."

"Follow-up treatment lasted for another six months. The mother's disease was completely under control. She had no relatives, and her death did not cause much commotion except for a few doctors."

"The child left with his mother, but the three years in the mental hospital had already caused irreversible impact on his growth. Until the night before he left, the child secretly ran to the corridor and said something to the door that no one could understand."

"After the mother and son left, I thought the dust had settled and everything was over, but no one expected that things would develop to a point where they were completely out of control."

"Only one year later, when the child was four years old, he was sent back by his father!"

"According to his father, the child's mother was killed at home and the child himself witnessed the whole process."

"When I saw this child again, he had changed a lot. His only support had collapsed. He was in the same state as when his mother first arrived at the hospital."

"Due to the child's previous performance, our hospital did not admit him and asked his father to take him to a large hospital for treatment."

"On the night we rejected him, at the first minute after midnight, blood began to seep out of the white-painted door of Ward No. 3 in Building 3."

"It lasted about a minute before it stopped. By the time I found out about this, it was already a week later. During this time, all kinds of bizarre things started to happen in the ward."

The second letter came to an abrupt end. Chen Ge looked at the words in the letter. Corresponding to the dean's description, he thought of someone who had the same experience.

He couldn't wait to open the third letter. In the envelope was a photo of a woman and a child. The moment he saw the photo, Chen Ge's mind was in turmoil.

He had seen this photo when he was helping Men Nan sort things out at Haiming Apartment!
