In 1985, the military medical team was ordered to rescue the third company of a railway corps unit that was in the critical stage of construction. The medical team center, Mo Li, Zeng Buyu, Zhao Yiqin, Wen Ting, and Wang Jianyun, have since formed an indissoluble bond with the soldiers of the third company. A few years later, they retired and started a new life. Zeng Buyu built a house in the suburbs of Beijing and lived a down-to-earth life. The relationship between the company commander Mu Jianfeng and Mo Li warmed up after they reunited, and Wang Jianyun and Wen Ting also talked about marriage. But Wen Ting was found to have a hereditary mental illness, so she took the initiative to leave. Mu Jianfeng felt ashamed of being inferior to Mo Li, so he quietly left and went into business and married Zhao Yiqin. Mo Li married someone else. In 1998, during the wave of reform, Zeng Buyu was inspired by the writer Zhou Zaipeng to transform his residence into Buyu Shanju, where his comrades occasionally came to reminisce about the past. A few years later, Wang Jianyun divorced and found Wen Ting to renew their relationship. Mu Jianfeng divorced, but he could not be with Mo Li in the end. Zhao Yiqin found a new life partner. At this time, Buyushanju is about to be eliminated in the market tide, but it will forever record the nearly half-life relationship and the purest emotions of these comrades.
