Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
hyoung gun » young eun
dong sind » dong sin, dong bin
dong ping » dong sin, dong bin, dong jung
yang jin » yang jie, yang jun, ying jin
gun hua » gui hua, tuan hua
hua ren » hua chen

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 ren ((yang di) OR (yang jin)) ((dong sind) OR (dong ping)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung gun hua ren ((yang di) or (yang jin)) ((dong sind) OR (dong ping)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung gun hua ren ((yang di) or (yang jin)) ((dong sind) OR (dong ping)) ;*.
