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 occurs 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 some bottles with the katydid design.
