First, let's consider some overall recommendations:
1. In regions where traditional Chinese characters are not used, it is not recommended to use traditional Chinese characters.
2. It is recommended that both the front and back sides have the same orientation, i.e., it is not recommended to have the front side vertical and the back side horizontal (nor should the front side be horizontal and the back side vertical).
3. Remember to check the back of the map and verify the specific demarcation lines for disputed areas within China's territory, so as not to "make a mistake."
Regarding the top: I noticed that you're using a dark color from the base map as the background color for the text/box, but I think it might be interesting to try using the red instead.
There's actually a logical reason for this: the base map itself transitions from "deep" to "red" in a downward direction. Therefore, whatever is at the bottom should continue using "red".
Back: Find an anchor point for the table's frame (width), such as "n" or "2n". This will make it look more organized than it does now.
