Porcelain tea sets are famous for celadon.

Celadon is famous for its delicate porcelain, bright and smooth lines, dignified and simple shape and pure and beautiful color. Porcelain industry has become an independent department in the Tang Dynasty. Lu Guimeng, a poet in the Tang Dynasty, once praised celadon with the famous phrase "When a kiln is opened in the autumn wind, a thousand peaks are green". Celadon is "green as jade, bright as a mirror and loud as a chime", which is called "the flower in porcelain" and is rare and precious.
