1950: Doctors Guard the Mountains and Rivers with Benevolence

After an accident, emergency doctor Chen Yan unexpectedly came to the battlefield where the War to Resist US Aggression and Aid Korea began. With his grandfather's concern for the heroes of the Volunteer Army and his original intention to protect lives as a doctor, he found that after his sacrifice, he could continue to stay in this land as different young volunteers - sometimes as a medical soldier crossing the line of fire, sometimes as a communications soldier passing orders, and sometimes as an ordinary soldier standing firm, witnessing and participating in this battle to protect his home and country at different positions. With modern medical knowledge and special medical support capabilities, Chen Yan always puts the treatment of the wounded first. He worked hard to allocate scarce medical supplies and used professional first aid techniques to help injured comrades. Especially in the severe cold of Changjin Lake and the artillery fire of Shangganling, he fought for the lives of endangered volunteer soldiers time and time again. Every time he successfully helps a comrade out of danger, he can continue to move forward more firmly, delivering urgently needed medical and communication support to the front line, and fulfilling his promise of "protecting heroes and protecting the country" with practical actions. This is not an easy journey, but one that endures under gunfire and severe cold. With the benevolence of a doctor and the respect of future generations, Chen Yan did his best on the historical battlefield, accompanying the volunteer soldiers to face difficulties and obstacles, and using his small power to add warmth and hope to this great war.
