In Tanjung Bulu Port, Jakarta, seagulls soar, and the sun shines on the sea. The hospital ship Heping Ark of the Chinese Navy, carrying out the mission of "Harmony Mission-2022", slowly docked at the dock. On the white ship, a bright and huge Red Cross stood out. In the cab of the hospital ship, the monitor Shen Xurong looked at the berthing position through the telescope. On the distant dock, many people were holding banners and small red flags, which looked like a red ribbon swaying in the sea breeze. Shen Xurong concluded, "That piece of red is the anchorage!" From November 10 to 18, under the influence of "China Red", this diagnosis and treatment area, which is less than half the size of a football field, is playing with stories of touching, friendship and peace every day. The Peace Ark is like a love bond, connecting countries and people closely. On a sunny morning, Professor Chen Feng, a cardiologist who was attending the clinic, received an old man in a wheelchair wrapped in a headscarf. The medical record handed over said: Eunice, 60, coronary heart disease. "Old man, what's wrong with you? How long has it been?" Chen Feng asked patiently, not missing any details, and the volunteers carefully paraphrased and translated. Chen Feng initially judged that the old man suffered from cerebral infarction in addition to heart disease. "I went to many hospitals and said that the problem was very difficult." The old man covered his heart and locked his eyebrows, as if he was holding back the pain, and handed over some previous examination materials: "I wonder if there is any hope of treatment?" Chen Feng carefully read the old man's medical record, asked her about her medical history in detail, and arranged an examination for her. "Please rest assured that your illness can be cured." Chen Feng told the old man, "This is coronary heart disease caused by blockage of heart blood vessels. The current state is relatively stable, and minimally invasive interventional treatment can be carried out, which is technically feasible!" Hearing these words, the old man seemed to see hope and said with emotion: "Thank you very much, thank the hospital ship Heping Ark!" During the mission, Chen Feng undertook three important tasks in the cardiology department, electrocardiogram and emergency room of the medical area of the wharf. During the reception, he successfully rescued three patients with syncope and hypotensive shock. On the same day, an elderly patient with chest pain for many years found Professor Zou Wenbin in the Department of Gastroenterology for treatment. "What have you eaten recently? How long has it been since you finished eating?" Zou Wenbin inquired about the medical history in detail, and carried out a comprehensive examination of him at the same time, finally diagnosed as reflux esophagitis. "One capsule in the morning and one capsule in the evening on an empty stomach." Through the examination, Zou Wenbin quickly gave the diagnosis, treatment and diet plan. After he had prescribed two boxes of medicine for the elderly, he explained the requirements and taboos of taking medicine to the elderly through translation volunteers, and wrote down daily precautions. During the recheck, the old man looked relaxed. He excitedly said to Zou Wenbin, "The second day after taking the medicine, the symptoms were relieved. After taking the medicine for 4 consecutive days, the chest pain did not appear once!" The symptoms of chest pain for many years completely disappeared, which made the tortured old man grateful. He wrote a letter of thanks to the medical staff, which said: "The best language in the world can hardly express my gratitude!" The average temperature at the wharf is above 31 ℃ every day. The medical staff adhere to the principle of life first and treat patients as relatives. Every day, about 100 patients are treated per capita
