这是一个古老的工艺,也是中国的非物质文化遗产项目。或许,自从中国有了紫砂和瓷器之后,这个行业可能就出现了。昔日,背着工具箱的手工艺人走街串巷,在糊口的同时将这项手艺一代代传承下去。 This is an ancient craft and also an intangible cultural heritage project in China. Perhaps, since China has purple clay and porcelain, the industry may have emerged. In the past, artisans carrying toolboxes went down the street and at the same time inherited the art from generation to generation.
