Please stay informed and actually go search and look at what the self imposed Taiwan Air Defense zone looks like. The United States Armed Forces drew a large square-ish shape in the sky which covered large land masses over China and declared it Taiwan ADIZ. The ADIZ of China and Taiwan overlaps over a large area. Btw airspace above Xiamen is included.
Edited for accuracy.
