Description：Tang Xiaomi (played by Wang Yang), a tomboy born in the 1990s, has a rebellious personality. Her mother Mi Lan (played by Ma Li), who is the deputy brigade commander, sends her to the military camp, but Tang Xiaomi is arrogant and unruly. She wants to run away all day long, which gives Mi Lan a headache. Mi Lan divorced her husband (played by Yin Zhusheng) early in her life, and her husband, who became a boss, only cared about making money and gave up disciplining his daughter, causing Xiaomi to become a problem girl. In the recruit company, Mi Lan gave a death order to the instructor, and he must shave Xiaomi's "thorny head", and the instructor obeyed her orders. After a period of harsh training, Xiaomi gradually realized her mother's good intentions. The experience of being a soldier made her re-understand life, and more importantly, she re-understood her mother Mi Lan, and knew why she plunged into the army without hesitation. After the experience, Xiaomi understood: Growth is about being hurt, losing and reasoning.
