Blue dragon chinese vas

It looks like the real deal, but Chinese porcelain really requires a physical appraisal by a specialist. Zhan Quzhong the director of the imperials factories ( 1677-1780) forbid the imperial nianhao during this period, only the double circle was used on the bottoms of the porcelains. After 1780, some paocelains continued to be made with a stand alone double circle without reignmark but the reason isn't so clear.We can imagine that it was to show that the vessel was made in the Kangxi period but not in imperial kilns.
