Several features suggest that this is probably an Imperial bottle, including the archaistic decoration, the eccentric shape, the flat, upper neck-rim and the fact that it is designed to be suspended - a feature of some known Palace bottles which often have loops around the neck for suspension cords. Conceptually it is unique, although there is a Qianlong Palace glass bottle which may be related, with a fenghuang instead of a bat (Robert Hall, March 2003). According to Cammann, the combination of the large and small bats (fu) imply a wish for happiness in large and small things. In addition, the design of a cash (with its rounded profile and square central hole) on the lip, with the sun and moon (possibly also implying happiness day and night) create an impression of the character ji (auspicious), while the archaistic clouds (yun) combined with the bat (fu) stand for fuyun, which conveys the same hope for good fortune. The leiwen design, being continuous, represents the continuity of the family line, a pressing desire in Confucian society.
