Perhaps you should try some spelling variations:
hyoung qiang » kyoung yang, gong qiang
wan hyoung » wang hyoung, man houng, min hyoung
dong sind » dong sin, dong bin, dong ping
yang jin » yang jie, yang jun, ying jin
yan jiu » yang jie, pang jiu
yang xi » yang di, yang yi, yang jui
1 best » 3 best, 4 best, 2 best

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: wan hyoung qiang ((als best) OR (1 best)) ((((yan jiu) OR (yang jin))) OR (yang xi)) dong sind ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan hyoung qiang ((als best) or (1 best)) ((((yan jiu) OR (yang jin))) or (yang xi)) dong sind ;~".
• Adding a wildcard symbol may retrieve word variants: wan hyoung qiang ((als best) or (1 best)) ((((yan jiu) OR (yang jin))) or (yang xi)) dong sind ;*.
