Frankly speaking, I've been through hell there too! I hate the arrogance and deceit of its people, though there are some exceptions I met who are not employed in the field of education. The Korean government has a duty to do something to improve the lot of migrant workers there, and to jail dishonest hagwon directors. That country is the pits for foreign teachers of English. Do yourself a big favor, avoid teaching in Korea.

By contrast, China is a great deal better, but it is by no means perfect. At least a foreigner can go out for a walk holding hands with an attractive native woman in a short skirt without causing a brawl to break out, or being the target of stones, thrown by envious male troublemakers.
