A light celadon colored jade was used to carve this bi disc. The disc itself is decorated with two writhing qilins and the characters 'Yi Zi Sun' which wish the recipient children with a great future. Qilins represent Wisdom and Harmony and are thought to bring sons with the ability to become high officials. On top of the bi disc is a carving of a boy on an animal which resembles a ram but is most probably meant to be a deer. The Chinese character for deer is 鹿 which is pronounced lu. The Chinese character 禄, which refers to a government official's salary, is also pronounced lu. A picture of a deer is therefore expressing a wish for a top government office with a high salary. The Chinese also believe that a deer lives to a very great age and, as a result, it has become a symbol for long life. The boy on the deer expresses the wish for many sons. Both sides of the bi disc are decorated in the same way. The disc entered the collection from Hong Kong in 1989 and it dates from the Qing period (1644 - 1912). Height 10.2 cm. Width 7.6 cm. Thickness 0.60 cm. Weight 84.5 grams.
