In 2000, in Jinghai Jiuchang Street, 9-year-old orphan Shen Zhiyi broke into Gao Qilan's life. Nine years younger than Gao Qilan, she was a timid shadow outside the police station on New Year's Eve, and the glimmer of light in the suffering of the Gao brothers and sisters. Shen Zhiyi was taken in by Gao Qiqiang and stayed with Gao Qilan day and night, becoming her closest sister. Gao Qilan grew up from a young female college student to a cold orthopedic surgeon. She always protected Shen Zhiyi under his wings and isolated the bloody storm of the Gao family's involvement in crime. Shen Zhiyi, with her purity and sobriety, held Gao Qilan in the swing between family love and justice.
