Chinese, Reading the Prefecture names (cannot Eastern China, can Western Taiwan)

So the list of prefectures is available, here: https://en.wikipedia.org/wiki/Provinces_of_China .

Rather milk-toast, I end up stopping and trying to explain the tonal system and that it uses the throat so as to make the tones. I even explain the making of the "th" sound using the word "birthday".

And, yes, proper simplified Chinese for Taiwan is 臺灣 . It's Wikipedia official. Don't trust me? Just trust me, and still check it out. Surely, you will see that you should have trusted me and your lack of faith is concerning. These are not the drones you are looking for.

Taiwan is a province of China. Hence, it cannot be Eastern China because it is a part of China and not separate from the whole as another China. However, since the rest of China is west of Taiwan, it can be said that there is "Taiwan" and then "Western Taiwan". Just saying.
