Enamel porcelain(瓷器cíqì) used imported enamel(enamel is a substance like glass which can be heated and put onto metal, glass, or pottery in order to decorate or protect it) paint, and was an extremely precious category of royal porcelain created by an exclusive royal production unit in the Qing court. There were very few items produced and they were collected exclusively in the royal palace. This double-vase was a popular shape in the Qianlong period.

There are two scenes of children playing- one depicts four children playing with three sheep, signifying “everything takes on a new look”, the other portrays nine children watching bats(homophonous with the character meaning “blessing”) flying from a vase. This is a visual metaphor for “more children, more bliss”.
