Asian Picture with Simple Goldwork Threading

Not sure how old this might be -- maybe about 40 years or so ?? Picture silk panel with some paint, some embroidery, and then some Gold work embroidery (threading) to make accents on the pic. Not sure what this is called of work is called - or if it has a special name. I thought it was neat as the Golding threading (? doubt if real gold ) gives off such neat accents to the Picture.

As for the wood frame -- it could have been a marriage at any time (I guess) as who knows....LOL. Know nothing of the mark on the frame either.

Any other info Welcomed !! Thanks
