In ancient times，copper coins meant wealth.Linking（连接） the copper coins（铜钱） one by one had the good meaning of collecting wealth.With coins，people can knit（编织） them into different shapes，from armor worn by the soldiers to protect their bodies from enemies and swords（剑），to animals and plants.As a traditional skill in China，copper coin knitting was listed as an intangible cultural heritage（非物质文化遗产） in 2018. 

Every day at 9 am, Zhang Canjin, 58, comes to the Drum Tower Street in Ningbo and walks into a small house. Sitting at his desk, the inheritor（继承人） of copper coin knitting starts his day. " Knitting the coins into different shapes doesn' t sound difficult, but the key is to be creative and think big, " Zhang said. 

So, since he started his own copper coin knitting store in 2014, he has tried very hard to think big. Zhang added, I have more creative ideas in my mind, " Zhang said. 

To try something challenging，Zhang spent two months making armor with more than 8，000 coins in 2017.It got great public attention and even got Zhang a national patent for design（设计专利）.This also gave him more confidence.Now he tries to continue getting more creative ideas and hopes the art forms will reach more people.

"I think we Chinese people should pass on our own treasure and tradition, " Zhang said. The house of Zhang stands there in the middle of the crowded Drum Tower Street, and inside Zhang is knitting his love for heritage into a beautiful dream.
