Construction engineer Du Fei completed the Africa Bridge project and rushed back to the hospital. The old man said Angkor's smile repeatedly while his grandfather Du Yuxing died. At this time, Du Fei accepted the invitation of the Construction Engineering Group to go to Cambodia to participate in the construction of Highway A of the Oriental Construction Engineering City. In Cambodia, he had a beautiful encounter with Cambodian girl Fangcao, a female teacher of a water elementary school, and started a beautiful and romantic pure love story. In the end, the two who had gone through ups and downs finally came together under the gaze of Angkor's smile.
