IMPERIAL, JINGDEZHEN KILNS, YONGLE TANG HALL MARK, DAOGUANG PERIOD (1821-1850)

Yongle tang, which may be translated as 'made for the Hall of Perpetual Joy,' is a rare hall mark that appears only on a small group of Imperial bottles from the Daoguang period. It is usually seen on bottles featuring the capture of Zhang Ge'er (Jahangir Khoja), and on some bottles, such as the present example, with the katydid design.
