A modern female emergency department doctor travels to 1975 and becomes an intern who is forced into marriage. She just wanted to treat illnesses and save people quietly, but found that every patient she saved was called a "miracle". From one person's persistence, to the changes of a department, to the establishment of a system. From the muddy ground of the county hospital to the editorial board of the national emergency medicine textbook. It took her ten years. And it all started in the summer of 1975, when an intern who was forced into marriage opened the door of the ward next door. "If the conditions are good, what else do you need?"
