Dear SeChan Yu,

Thank you so much for reaching out, and for the lovely compliments on our website. We are happy that you are able to find some use out of our materials! As for the naming of this particular body of water, we definitely appreciate and understand that it is an important topic for a number of people. We try our best to include both alternate names on our world map, and also to provide an unbiased overview of the different approaches that various internal governing bodies take on the matter. You can find more about that here:

Again, we do appreciate you reaching out, and we wish you the best of luck in your studies!

Warmly,

Rachel
