It was in the pristine and passionate 1970s in the field hospital of the army on the southern front. Fang Jie, Ye Wei and Mou Xiaohua, a group of cadres' children and Fat Fu and Liu Lianhua, children from ordinary families, have differences from the first day they became soldiers. But all this conflict is accompanied by the rigors of army life, and a fusion begins to emerge. In the end, they become the closest comrades and female companions. This period was accompanied by trials of life and death. It was accompanied by political trials. Because of their different personalities and family backgrounds, they adopted different attitudes in the face of the test of life and death, and their military life was like a kaleidoscope. Around them was a group of old comrades. These soldiers who joined the revolution from the 1940s to the early 1960s, because of their own different upbringing, also adopted different ways of education for these female soldiers. It can be said that without them, there would be no female soldiers growing up.
