The "Tiexi District" on the edge of Tongcheng is an urban village transformed from a former state-owned enterprise family home. It is a mixed bag of migrant workers and local unemployed people. The Song family lives in an old building called "Eight Buildings". The house was allocated by his father Song Jianguo in the factory when he was young. The buildings are mottled and the neighborhood relations are so close that it is suffocating. The timeline had already happened before Song Ci crossed over: his younger brother Song Di was abducted at the age of five (original history); Song Jianguo owed an underground casino loan shark of 60,000 yuan; his mother "ran away from home" two years ago and there was no news again.
