The first chinese character on the top left on the bottom of the bottle means “Made for Qianlong”. This character is present only on few bottles because of its imporance: those pieces were the ones selected for Emperor Qian- long (reigned 1736-1796) for their extraordinary artistic quality, representing the very best of craftmanship. On each side there is a bucolic scene with flowers and leaves. Only in one there is a bird. Those are typical iconographic natural motifs of the period.
