After returning to his hometown, Feng Xiaozheng wants to make a giant kite that requires multiple people to pull, but faces Master Feng's test due to his bold idea. He earnestly studies from the bamboo strip framework and tying lines to painting and flying, understanding wind force, structure, and traditional rules during the initial test flight and continuous adjustments. Su Xiaofeng assists in advancing the cultural center and experience activities, and everyone also improves the materials and kite strings. After the cultural center opens, traditional kites and new works are flown together. Finally, Master Feng hands the old bamboo slicing knife over to Feng Xiaozheng, letting the kite string by the sea connect old craftsmanship with youthful creativity, continuing to fly towards a more distant sky.
