Municipal People's Hospital, a busy and dramatic little universe. Lin Yuan originally wanted to live a low-key life, but was slapped in the face by reality. From the thrilling scene at the rescue station, to the gossip storm at the nurse station, to the bizarre stories between doctors and patients; the director who doesn't like to name names, the interns who like to make mistakes, and the logistics team where rumors are flying everywhere. Between the duty schedule and the cases, Lin Yuan and Xu Qianyu, Ouyang Da, Zhao Mengmeng, Ma Huifen and others experienced misunderstandings, conflicts, reconciliation and growth in absurd and tender incidents. They have become each other's most solid support side by side in the bitter and sweet hospital life, with laughter and tears. When the hospital encountered public opinion crisis, policy turmoil and medical ethics test, the "white warriors" withstood the waves with humor and wisdom, guarding the glory and warmth belonging to doctors at the end of the lifeline. The book is ups and downs yet simple and clear. In the ward where noise and tranquility, laughter and tears intertwine, it writes a unique group portrait of the Chinese medical workplace.
