Beijing's Palace Museum, also known as the Forbidden City, has an ongoing porcelain exhibition that promises visitors a wide view of imperial China.

While historically, many porcelain pieces have similarities in their facades, styles and patterns, only the most stunning ones were taken to the Ming Dynasty (1368-1644) courts from the renowned porcelain hub of Jingdezhen in eastern China's Jiangxi province.

Imperial Ceramics and Porcelain of the Great Ming: Comparison of Excavated and Extant Ceramic Pieces from Hongwu (1368-98), Yongle (1402-24), and Xuande (1425-35) Reigns, is the show that now presents some 297 sets from collections of both the museum and the Jingdezhen Archaeological Research Institute to offer people a more thorough understanding of the ancient ceramic industry.

"As a place that made porcelain for emperors, the royal kiln in Jingdezhen had very high standards for its products," says Shan Jixiang, director of the Palace Museum. "Once there was the slightest blemish, the porcelain pieces were broken and buried."

However, the defective ones are also important historical references for modern society, according to Geng Baochang, a veteran researcher at the Palace Museum.

For example, an exhibited jar restored from broken pieces of porcelain reveals that it was originally made for Emperor Xuande, who was a fan of cricket fighting, a blood sport similar to cockfighting. But none of his cricket jars in the palace survived.

"The porcelain collection in the Forbidden City has a clear linage, and the different layers of earth also distinctly indicate the ages of these broken pieces, which provides abundant references," Geng says.
