Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
gain yang » dan yang, tan yang, yin yang
daun yang » dan yang, tan yang, un yang
yan yuan » yan guan, fang yuan, yan clan
wang wei » zhang wei, wang zhi
nan yan » nan ya, wang yan, qian yan
yi wang » li wang, yi gang, yi yang

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 ((yan yuan) OR (nan yan)) ((((gain yang) OR (daun yang))) OR (du yang)) yi wang wei ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((yan yuan) or (nan yan)) ((((gain yang) OR (daun yang))) or (du yang)) yi wang wei ;~".
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((yan yuan) or (nan yan)) ((((gain yang) OR (daun yang))) or (du yang)) yi wang wei ;*.
