Didn't I Just Leave the Army? Why Am I Back in the Unit?

Lu Zheng is an honorable soldier in the People’s Liberation Army. Just as he is preparing to embark on the next stage of his military career as a senior noncommissioned officer, disaster strikes at home: his father is critically ill. Under immense pressure from his family, Lu Zheng has no choice but to leave the army and use his severance pay to cover his father’s treatment. It is still nowhere near enough, however, so he has to find a way to earn more. As it happens, a call from his former commander gives him an opportunity.
