I was in the mountains of Yangminshan in Taiwan during Christmas and my allergy that I was suffering from in China completely disappeared due to the clean, fresh air there. Now back in China and the histamine has started once more. There are two teachers at my school in China whose spouses have managed to obtain work at the school. They are only paid a local Chinese salary though and their salaries are paid through their spouses as they do not have a work visa. So it is possible to work in China as a couple. It's cheap labour really for the school but this has been discussed at length on another thread. Chinese corporation-owned international schools (mine is intl not bilingual) are cutting down on costs it seems wherever they can. TEFL teaching is abundant in Asia not just China. Korea for example has hundreds of language schools called hakwons. Your husband could get a job at one of these without a problem with just a BA and being a native speaker. You don't have to have a TEFL to teach in Korea or China although it helps. You only really need a TEFL to teach actually in the UK or in Europe. Everywhere else it is optional unless it is say working for the British Council and then you would require one.
