Perhaps you should try some spelling variations:
hyoung ya » young a
hyoung il » hong il
tong shui » tong hui, cong shu, gong hui
long shu » cong shu
hua see » chua tee, chua yee
yan jiu » yang jie, yang jin, pang jiu
long du » long d, long do, long run
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((hyoung ya) OR (hyoung il)) hua see yan jiu ((((long shu) or (tong shui))) or (long du)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((hyoung ya) OR (hyoung il)) hua see yan jiu ((((long shu) OR (tong shui))) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hyoung ya) OR (hyoung il)) hua see yan jiu ((((long shu) or (tong shui))) or (long du)) ;*".
