Five years ago, Yuanshan Cold Chain, managed by Chen Tianming, was on the verge of bankruptcy, and he begged his younger brother Chen Ran for help. Chen Ran mortgaged his property to invest funds, personally remodeled the old cold storage, and built a partitioned independent temperature-control system. Relying on his unique on-site temperature control experience, he built Yuanshan Cold Chain up step by step. However, Chen Tianming socialized all day, completely failing to understand Chen Ran's technical value, and only felt that his younger brother was just guarding the cold storage temperature. After the business got on track, Chen Tianming grew wary of Chen Ran's ability, teamed up with his confidant Li Kai to plot and squeeze him out, seized the cold storage management rights, and swept Chen Ran out the door.
