Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung gun » young eun
gun hua » gui hua, tuan hua
wei yan » wei yang, wei yuan, wai yan
yan jiu » yang jie, yang jin, pang jiu
long du » long do, long did, long des
long d » long do, long _, long 2

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung gun hua wei yan jiu ((((long du) OR (long run))) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung gun hua wei yan jiu ((((long du) OR (long run))) or (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung gun hua wei yan jiu ((((long du) OR (long run))) or (long d)) ;*.
