Beautiful baluster vase in Chinese porcelain called "blue white" from the end of the 19th century.We can see decorations of blue characters on a "celadon" background. It is a color specific to China representing a shade of green which is also called "qingi" which translates to "green porcelain". Over time, the color fades. The figures in blue are probably Taoist immortals. This belief in the immortal precedes the appearance of Taoism. Taoism is one of the three pillars of Chinese thought along with Buddhism and Confucianism. It is based on the existence of a principle which is at the origin of everything, the "Tao". As for the immortal, he represents in China a fantastic being who possesses supernatural powers and cosmological dimensions.
