After finishing the drawing, she explained how to use it, "Just thread it through a row of corn cobs, and they will all be pierced.

The mill owner listened beside her, nodding nonstop, his eyes beaming with joy, "This thing is easy to make! We can make one quickly!"
"Tie Zhu! Go get the tools, and let's make one right now!" Grandma Sun urged her son.
"Wait first, this is the simple one. There is another one that is even more convenient!" Pei Qin stopped him.
Sun Tiezhu waited for her to continue drawing.
