Method 1: Find a picture that matches the outline pattern and open it as the background picture. Open the calligraphy work again, use the "Move" tool to pull it onto the previously opened background picture (there are two layers at this time), use the "Edit \ Free Transform" tool, hold down Shift, and pull the four corner adjustment points to adjust their size and position until it is appropriate (you can adjust two layers separately). You can also add axes up and down (you can find ready-made axes or draw them yourself). When finished, merge the layers and save them as another JPG file.
Method 2: Find the frame image file suitable for this frame and open it. Then open the calligraphy works. Pull it to the border image file, resize and position it, and save it as a JPG file.
