I suggest you go to a website such as http://www.orbitz.com and tell it you are doing a multi-city flight. Then you enter the destinations and dates of travel. Do it one for London-Seoul-Hong Kong-London and then do 2 round-trip searches, one for London-Hong Kong and the other is Hong Kong to Seoul.
Whichever one gives you the lower price is the one you go with. Another option is to visit the websites of Jeju Air and Jin Air. These are 2 low-cost airlines that fly non-stop from Hong Kong to Seoul.
Jin Air is a subsidiary of Korean Airlines.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
