Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang liang » wang liang, yan liang, yang yang
yan clan » das clan, yan guan, yan yuan
tan ying » fan ying, ran ying, tan yang
ying jin » yang jin, jing ji, yang jie
jin dang » jin kang, jin chang, jing fang
nan yan » nan ya, wang yan, qian yan

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 ((((yang liang) OR (yan clan))) OR (nan yan)) tan ying jin dang (hai OR haji) ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((yang liang) or (yan clan))) or (nan yan)) tan ying jin dang (hai or haji) ;*.
