Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
qian wang » yiqian wang, qian rong, qian yan
yan wang » yuan wang, yang yang, yan liang
juan tan » huan t'an, juan rana, juan a
tan ying » fan ying, ran ying, tan yang
ying jin » yang jin, jing ji, yang jie
jin kang » jin chang, jin kyung, jing fang
tae » take, tape, tale

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: nan ((((yan wang) OR (qian wang))) OR (yang guang)) juan tan ying jin kang tae ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan ((((yan wang) OR (qian wang))) or (yang guang)) juan tan ying jin kang tae ;~".
• Adding a wildcard symbol may retrieve word variants: nan ((((yan wang) OR (qian wang))) or (yang guang)) juan tan ying jin kang tae ;*.
