Qinsihe has collected letters from all patients since they were admitted to the medical field, with a total of more than 11,000 letters. The reporter carefully opened more than a hundred of them. The letter paper from thirty or forty years ago was yellow and crisp, but the pain and hopes contained in it were still fresh:
"The horizon has been tilted in my eyes for more than 20 years. I hope to become a healthy person day and night. Even if I spend the second half of my life to exchange for five years of healthy life, I will agree without hesitation!"
"After I got polio at the age of 3, my world was only left with the earthen kang and the surrounding walls. I have lived so big that I have not looked in the mirror a few times and I am unwilling to move in the sun. Through the streets where people come and go, it is my saddest time. Uncle, I also have to stand up and walk, hoping to get your help!"...

Back then, Qin Sihe reads letters from patients two nights a week, and every letter must be read. Many envelopes said preliminary judgments such as "coolable", "coming hospitalized on a certain month and a certain day", and "unsatisfied results", and then they replied to the patient one by one. He said that disabled patients have difficulty moving and have a long journey, so they adopt the "arrangement system" to save them money and labor. In the letter
, the patient expressed his gratitude to Qin Sihe. In the operating room, the patient suddenly bleeded. Qin Sihe rolled up his sleeves without hesitation and donated blood on the spot. On the Mid-Autumn Festival, Qin Sihe paid for money to buy mooncakes and pastries for the hospitalized patients to celebrate the festival together. Qin Sihe's own foot had surgery because of his fan-shaped foot. Not even half a month after the operation, he wrapped his feet in gauze and wore a blue and white patient gown. He leaned his crutch against the patient's bed, knelt on the bench with one leg, and performed surgery on the patient...
In the letter, there was also a huge joy of the patient seeking medical treatment: "In your firm words and calm expressions, I captured the confidence of success." "You gave us disabled people a second life." A farmer from Tanyi Town, Fei County, Shandong Province happily reported the good news to Qin Sihe: After he cured his legs, the couple became the first local pig farmer, and also passed on the experience of getting rich to other disabled people without reservation. Some patients call him "Qin Daxia" and "the world's number one sword".

Qin Sihe never worries about doctor-patient relationship issues, and all his energy is spent helping patients solve problems. The patient brought insoles, cotton jackets, and even cart apples and seafood... What he was most happy about was that when he was going out for meetings and consultations, he met a patient he treated many years ago. He likes to see them look fat and full of children and grandchildren, and likes to take photos with them.
In these photos of reunion after a long time, the reporter saw that both men and women like to hold Qin Sihe's hand or hold his arm, just like holding his brother or father. Qin Sihe's smile was even more intoxicating, as if showing his best works. (Reporter Yang Xueying and Wang Shixiang of Dazhong Daily Client)
