The invention of paper has been attributed to the Han Dynasty, supposedly realised by a court official and presented to the emperor. Paper had major impact on the dissemination of Han literary and artistic culture. Zoomorphic paperweights made in clay, stone and bronze were abundantly produced in the Han Dynasty, as important study tools used by ancient Chinese scholars.
The pig has a long history and standing within Chinese culture. As a symbol of the Chinese zodiac, the pig symbolised prosperity and happiness.

Both the poor and wealthy elite considered the pig a vital symbol to their culture.
