Yuan blue and white porcelain was passionate,bright,and unrestrained,reflecting the ultimate beauty of artificial craftsmanship.Some people believe that Yuan blue and white porcelain was a giant when it was born,unlike other porcelain varieties,it had a development period.From the high ancient celadon before the Tang Dynasty,gradually following the development path of Tang Dynasty folk kilns,Northern Song Ru kilns,Southern Song official kilns,Song kilns,and finally reaching the pinnacle of celadon at Longquan kiln,one can observe step by step how celadon has grown.Yuan blue and white porcelain does not have this gradual process.When it is presented to people,it is already a mature posture like a towering tree.
