One hand is the humble livelihood of picking up waste paper, and the other hand is the grand dream of lifting the stars.
In a barren mountain village, single mother Lin Xiujuan uses her blood and sweat to irrigate hope. She is not only a mother who endures hardships, but also a hidden genius. Her son Chen Xinghui inherited her amazing talent. He used charcoal blocks by the stove fire to calculate formulas and used tree branches to solve aerospace problems by the stream.
When the county competition became a sensation, when the mystery of his life experience was gradually revealed - what was left on that stormy night was not only the star-shaped mark on the back of his hand, but also the blood bond with Shen Yuzhou, the chief scientist of China's aerospace industry. From a poor student to an international Olympiad champion, from a child in a mountain village to a rising aerospace star, Chen Xinghui walked step by step toward the stars and the sea under the guidance of his mother's embroidery needle.
Lin Xiujuan never thought that her unique stitching method in embroidery would coincide with the laws of the universe and become the key to solving cutting-edge problems such as quantum communication and orbit calculation. This is a legend of mutual achievement between mother and son, a perfect fusion of traditional wisdom and modern science, and an epic story of a poor family's counterattack.
When the embroidery needle meets the spacecraft, and when the calculations on the stove illuminate the interstellar orbit, they use the simplest way to write the most shocking space legend.
