Rongbaozhai, meaning the Studio of Glorious Treasures, has preserved a dozen valuable works, including a lot of national cultural relics, such as a piece of Tianhuang stone weighing 4,275 grams, the heaviest of its kind in the world.
Rongbaozhai's history could date back to Qing dynasty, 300 years ago. Its predecessor is Songzhuzhai, which sold art, writing paper and "four treasures of the study" (brushes, ink, paper and ink stones). Its paper was once selected and used in imperial civil examinations and this gave the shop great prestige and promoted the sale of its goods. But later as the economic and political situation went bad, Songzhuzhai's business was heavily hitted and was in great debt. Later the owner of Songzhuzhai appointed another person to manage the shop and replaced the shop's name as Rongbaozhai, which means a place of masters, friends and the glorious treasures. By their unique skills in watercolour block printing, Rongbaozhai finally survived and become well-known afterwards.
