Well, Han-wu is considered more as a gift and occasional treats in Korea, rather than simple ingredients or cuisine. If you go to any website that exclusively sells Han-wu like this random one from google (http://adhanwoo.co.kr/) you will see what I mean. I was just trying to point out a particular Korean culture about Korean beef. (Funny thing is only beef has this trend - we don't do gift with pork or chicken D)
