I want to know the best regions in South Korea as a whole to live in?, What's about the languages spoken? What's about to find an accomodation and the average rent? Is it easy to find a job, especially in sales/ management in the sector of Beauty and cosmetics? The work permit is it easy to get it?, Is it a secure area? Are there different sorts of entertainment, what's about local and international restaurants? , the climate? etc..
Thank you,
