Christmas at Myeongdong is chaos! I went there around 5 pm on christmas eve, and there were lots of people but still easy to walk. After about 1 hour it got pretty bad :P
I tried to swim through the mass of couples & friendgroups there, and I dont know how long it took to get from one end of the street to another... In Korea christmas means shopping! Its not so much of a family thing like in Finland, its more for couples.
Lots of "free hugs" available also :----D
p.s. This is in english coz I dont have finnish keyboard here, LoL
