Qianyun

Tiansuo Engineering, China's 6G stratospheric communication platform, has had three test flights and three cable breaks. The project was on the verge of being abolished, and deputy chief engineer Shen Qian was demoted back to Weifang, the city of kites. Foreign companies are about to cut off supplies. An international patent crackdown followed. Everyone said that this project was hopeless. Until Shen Qian saw a Qing Dynasty kite in the Kite Museum. With just three regular knots at the tether, the line never gets kinked no matter how windy it is. In the manuscript left behind by my grandfather, there are forty-seven kinds of knots, which contain two thousand years of kite wisdom. Three points of tension. Follow each other step by step. Borrow the wind and give way to the wind. Every knot is the answer to the engineering problem he struggled to solve. Later, someone laughed at him: "You want to use kites to build 6G?" He tightened the string in his hand: "If you hold the string and don't fall off, it's a kite."
