Is Taichung abc/cbc friendly city for teaching?

Back on topic. My wife was born in Taiwan but raised in the US (since 3 years of age). Her primary language is English. She got a job teaching English when we were in Taiwan but was fired because too many parents complained that a “Chinese person” was teaching their children English. Nevermind that my wife speaks English with a North American accent, speaks only basic Mandarin, knows very little about Chinese culture, and considers herself American. The ignorant parents wanted a white face, and she didn’t fit the mold.

And this was in Taipei. I question whether Taichung or any place in Taiwan at all is truly “friendly” to FBC English teachers.
