Perhaps you should try some spelling variations:
hyoung qiang » kyoung yang, gong qiang
dong sind » dong bin, dong ping
yan jiu » yang jie, yang jin, pang jiu
yang yi » yang di, yang xi, yang jui
1 best » 3 best, 4 best, 2 best
wang » wing, wan, lang
sind » signd, skind, seind
sin » sign, skin, sein

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