Ting Shao Kuang - print? Painting? Gauche?

I found this Friday at my regular thrift store & a image search showed it's by a Chinese artist Ting Shao Kuang.
One I found was described as gauche on paper that looks like mine - except mine is a 1/2 inch larger all around & that one has space under her feet where mine ends.
I didn't think there could be 2 of the same & thought mine was a print, but it looked so good under a magnifying glass that I took this one out of its frame.
After taking the brown paper off the back there was a unusual cross support? made of cardboard or thick paper that didn't offer much support - any reason for it?
After taking it out of the frame I found the art is mounted on board with a silk? trim that has designs in it? (last 2 photos, 1st one you can see at 3:00 & 5:00 position on a clock)
Is mine a painting? A gauche? I can feel different textures & with a magnifying glass see some small bumps in the colors?
What do I have?
Thank you!

 

Here is 1 gauche on paper

Here is a serigraph on rice paper that the description sounds like mine - I think?

Thanks again!

This artwork titled "Ancient Civilization" 1996, is an original color serigraph on thin rice paper taped to a sheet of wove paper for stabilization by noted Chinese artist Ting Shao Kuang, b.1939. It is unsigned as issue. There is a hand signed and numbered edition of the same image. The artwork (image) size is 24 x 23.35 inches, rice paper sheet is 28.5 x 27.25 inches, backing wove paper sheet is 30.5 x 29.25 inches. This artwork is a trial (test) proof. The printer will print the same subject in different colors combination for the artist to select the one he want for producing the final signed and numbered edition. Some of these trial proof are unique as only one copy was printed with these particular colors. It is in excellent condition, the margin is slightly wavy.

 

I think it is a serigraph, and I like it.

But you may want to change 'gauche' to 'gouache'.
Gouache is pronounced goo-wash (sort of).

 

Gentle reminder above that you don't want to be gauche by misspelling gouache.

Ditto
Gouache,like tempera would dry very quickly if used to create a silk screen (serigraph),a retarder would be needed.The 'retarder' slows down the paint's rate of drying.If you didn't slow the pigment's rate of drying-the paint hardens & clogs the screen,partly obliterating the image.
