They make the maps doubly illegal if Taiwan is shown with different colors indicating an independent country ;) never mind the Spratleys, Senkaku, etc.
However, it's one thing to have some "official view" and another thing to brainwash citizens into thinking that these countries really are one, as they practically aren't. I was asking about the latter.
For example, some EU regulation classifies snails as fish to make their production eligible for fishing subsidies, but in biology textbooks they still remained molluscs.
You need to develop some subtlety to be taken seriously.
The troublesome part is coloring land not theirs as theirs in the map as well as labeling India's "hat" as disputed. There ate disputed lands, but not as large as implied.
And it seems that Taiwan is indeed same color as PRC. They really are crazy.
