GU=箍,"GU" is a chinese traditional folk handcraft seems to disappear because of modern industry.A "GU" craftsman use metal wire which looks just like stapler nail we using now to repair broken porcelain and crockery.When I was a child,I felt it's so amazing because the ceramic is too frangible to be dug a hole on it.And sometimes the result is more beautiful and the original...Time To Remember.
