live in Taichung and work in Miao-li?

Hi. I’m new to this forum and will highly appreciate your advice, because I should move to Taiwan for longer period of time pretty soon:-) Does it make sense to work in Miao-li while living in Taichung? Is there any expat community in Taichung and what should I expect in terms of daily connectivity to Miao-li by public transport or by car?
