Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
yuan chang » yuan cheng, huang chang, han chang
yan liang » yang liang, wang liang, you liang
ying yuan » fang yuan, meng yuan, yan yuan
chang hai » chang ha, shang hai, change has
qian yan » qian jun, qian yi
tan ying » fan ying, ran ying, tan yang
wang » wing, wan, lang

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: wang hyoung ((((yan liang) OR (yang guang))) OR (qian yan)) tan ying yuan chang hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang hyoung ((((yan liang) or (yang guang))) or (qian yan)) tan ying yuan chang hai ;*.
