Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yang liang » wang liang, yan liang, yang yang
kang haji » dang hai, kang han
yan guan » gan guan, yan yuan, yang guang
qian yan » qian jun, qian yi
ran ying » fan ying, tan ying, jin ying
ying jin » yang jin, jing ji, yang jie
jin kang » jin chang, jin kyung, jing fang

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 guan))) OR (qian yan)) ran ying jin kang haji ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((yang liang) or (yan guan))) or (qian yan)) ran ying jin kang haji ;*.
