Xu Fengxian, an inland river buoy maintenance worker, works with seaweed at the junction of saltwater and freshwater every day. Her tools are a long soft brush and a high-pressure water gun. Her credo is to "clean the buoys appropriately" - if you apply it hard, the anti-corrosive paint will be finished first, leaving a thin layer of algae to protect the coating. Her ex-boyfriend Shen Du is a waterway inspector and believes that buoys must be absolutely clean - any algae residue may entangle the anchor cable and drag it off the mark, which could cost lives. We broke up five years ago. One thought the other party was too arrogant, and the other thought the other party was too lazy. Now that the rivers are reunited, one wants to "remain" and the other wants to "clear", and no one wants to retreat. On a rainy night, No. 3 Was dragged out of place by algae, and Shen Du risked his life to deal with it; during the assessment, Xu Fengxian's algae retention plan got high marks. Both of them were looking for that "degree", but later they found that they were no longer themselves if some of their bottom lines retreated. The river is wide, and everyone has their own way of moving, but the buoys have their own limits to escort the ship, and the lover has their own limits to protect the sincerity.
