Courtyard House: I, the eldest son of the Jia family, have returned from the battlefield.

Jia Dongming, a veteran, was transferred to the security department of Hongxing Steel Rolling Mill after killing prisoners of war. On his first day, a casual remark from Deputy Factory Director Li, "Have Sha Zhu cook a couple of dishes," triggered a flood of memories: He Yuzhu, Jia Youcai, Zhang Cuihua… He had become the eldest son of the Jia family in the courtyard, a family that should have died long ago. This steel rolling mill held more than just the position of security chief for him; it also held the Jia family's messy debts.
