Chu Qingzhi gathered the children and laid out the colorful strings on the table, starting to teach them knotting, beginning with the simplest design, a copper coin shape.
The copper coin was brown, so she used brown-colored string, adopting a double coin knot technique. Under Chu Qingzhi's skillful hands, after a series of knots, the string transformed into a copper coin.
One child clapped in amazement, "Wow, sister, you're so skilled."
Chu Qingzhi asked everyone, "Did you all see how I did that clearly?"
The children shook their heads, except for Zhang Lingmei, who nodded, "I saw it clearly, sister. Let me show you."
She took a brown string in her hand, folded it, flipped, threaded, and pulled, creating a copper coin.
Chu Qingzhi examined the copper coin in her hand, "Not bad. Teach your brothers and sisters next. Start with making five hundred. I'll buy them from you for two coins each."
