Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang liang » wang liang, yan liang, yang yang
yan yuan » yan guan, fang yuan, nan yan
qian yan » qian jun, qian yi
tan yang » dan yang, tan ying, tan yong
yang jie » yang jin, yang di, yang jui
jie dang » jie zhang, vie dans, bie dans
hai » hadi, haji, hari

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 yuan))) OR (qian yan)) tan yang jie dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((yang liang) or (yan yuan))) or (qian yan)) tan yang jie dang hai ;*.
