Ive not worked as an Eva air FO but ive lived in taiwan as an expat and can tell you that its a great plade to live. In fact id say that its underrated.
Cost of living is cheap, its super safe in all respects and it has one of the best health care systems in the world. Its also very modern. You can also pick up mandarin.
As an American youd also appreciate how Taiwanese love Americans right now. Many people speak English too.
Some of the disadvantages are that its humid (more than texas humid). But the winters are mild and some places are very bearable like Taichung.
If you have questions about living in Taiwan feel free to pm me. Ive lived in Taiwan for 3 years and am married into the culture. Ive also lived in Asia for ten years.
