Not to jump in the middle of this fight, and I don't speak Chinese (only Japanese), but the text on the mat in your photo says that its a replica (複製) of a work in the 国立故宫博物院 (National Palace Museum in Taiwan). The printing (or painting) in gold appears to be a gimmick (none of these works would have been originally painted that way, and it states that its a "gold color replica" on your mat. Some sort of museum gift shop item, I'm guessing.

Its hard to see from your images, but I'm guessing one is a reproduction of "Early Spring" by Kuo Hsi, and one of the others "Wind in the Pines Among Myriad Valleys" by Li T'ang. You can find images of these on the National Palace Museum's website. I'd search around more, but the website is being wonky for me.
