Photo taken on Dec. 18, 2011 shows a piece of classic-style Sancai porcelain work, which depicts a Tang-Dynasty servant maid, at a Sancai technique museum founded by local artist Gao Shuiwang in Mengjin County, Luoyang, central China's Henan Province. Mr. Gao is a leading figure in the revival of Sancai, a Chinese porcelain characterized by a glaze with three intermingled colours. The producing technique of Sancai, which dates back to the Tang Dynasty (618-907 AD), was listed as one of China's National Intangible Heritages in 2008. (Xinhua)
