Perhaps you should try some spelling variations:
hyoung tan » young man, hong tan
hyoung gun » young eun
asia wen » asia why
chia wen » china won, ching wen, chia lan
jiu long » jiu cong, au long, eu long
long shu » cong shu, tong shui, long du
yan jiu » yang jie, yang jin, pang jiu

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 OR lang) ((hyoung tan) OR (hyoung gun)) ((asia wen) OR (chia wen)) yan jiu long shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wan or lang) ((hyoung tan) or (hyoung gun)) ((asia wen) OR (chia wen)) yan jiu long shu ;~".
• Adding a wildcard symbol may retrieve word variants: (wan or lang) ((hyoung tan) or (hyoung gun)) ((asia wen) OR (chia wen)) yan jiu long shu ;*.
