This industrial and administrative city, the capital of Gyeongsangnam-do is situated on a site that was mostly farm land and rice paddies in the 1960's. The planned nature of Changwon can be seen in the wide avenues (wide enough to be able to serve as air fields in case of war) and neatly designated factory and business districts. A major benefit to living/staying in Changwon is the biking convenience. The city has bikes that can be rented monthly (if you provide a phone number), and these bikes receive plenty of accommodation with the plentiful and spacious bike paths.
Most travelers to Changwon are there on business though there is a large foreign community of English teachers along with many factory workers from all over South-East Asia. Besides being a transportation hub Changwon has a gigantic entertainment district with countless bars and restaurants.
Because it's such a new city, Changwon can feel severely lacking in cultural activities, especially when compared to other Korean cities. The city doesn't make it into most major guide books for Korea, but if you dig a little, you can easily find things to do. There are some beautiful temples, lovely parks, and plenty of festivals, museum, and musical events.
