Li Shaocong is a technician who repairs the foam layer of cold chain insulation compartments. He works with polyurethane and styrofoam every day, repairs the gaps in the compartments, and also tries to repair the cracks in life. Three years ago, Lin Wei, a freight dispatcher in the same city, broke up with him. The reason was that they were together less and separated more, and their love was exhausted. Three years later, an emergency repair caused the two to meet again. She was still the busy scheduler, and he was still the technician who stuck to his craftsmanship.
The foam layer can make up for the air conditioning in the car, but it cannot make up for the temperature difference that will last for a long time. When a batch of vaccines worth tens of millions faced scrapping due to cracks in the car body, and when long-distance bumps caused all the joints of the old and new foam layers to crack, they were forced to stand on the same front. The pull of craftsmanship, the rekindling of emotions, and the hidden rules of the industry are all happening in this world of cold chain transportation.
Li Shaocong has repaired the loopholes in thousands of refrigerated trucks, but he has never been able to repair the deepest hole in his relationship. Until he discovered that some cracks needed not to be filled, but to be understood. Some temperatures are not maintained by the insulation layer.
