I only have the one item by them - a blue and pink paperweight style piece.
The top view appears to show a chinese symbol in its centre.
The side on view shows the butterflies better, and also shows chinese characters low on the side
The signing reads 'LLGF @@@@ - 2005 - 1585/3000' which tells me it was made in 2005 and is from a limited edition as #1585 of 3000. The @@@@ are Chinese cahracters I have no idea what they say. LLGF = LiuLiGangFong which surely made signing a little simpler.
