Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
yan liang » yang liang, wang liang, you liang
daun yang » dan yang, du yang, tan yang
jin chang » chin chang, joon chang, ying chang
chang hai » chang ha, shang hai, change has
yan guan » gan guan, yan yuan, yang guang
qian yan » qian jun, qian yi
yang jin » yang jie, yang jun, ying jin

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 liang) OR (yan guan))) OR (qian yan)) daun yang jin chang hai ;~.
• Adding a wildcard symbol may retrieve word variants: lang hyoung ((((yan liang) or (yan guan))) or (qian yan)) daun yang jin chang hai ;*.
