Papercuts, kites, jade and other stone carvings, cloisonné, wooden toys — these arts with ancient roots in China are still widely practiced, especially among ethnic groups. Noted for their exquisite workmanship, some Chinese crafts use simple materials like scissors and paper in the case of papercuts while others use materials that are elegant and expensive, as in jade carvings. China's cloisonné — inlaid enamel — is popular both at home and abroad in products that include bottles, bowls, and cups. The blue glaze produced during the Jingtai reign period (1450-1456) of the Ming Dynasty Emperor Daizong is considered the best.
