Perhaps you should try some spelling variations:
hyoung yang » kyoung yang
chang ann » chang min, chang won, change annex
chang yun » chong yun, chang hsun, chae yun
can when » can women, can we, can win
han shen » khan sher, can she, han en
hong yu » wong yue
wang » 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 OR wing) hyoung yang ((can when) or (han shen)) ((chang ann) or (chang yun)) hong yu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) hyoung yang ((can when) OR (han shen)) ((chang ann) OR (chang yun)) hong yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang OR wing) hyoung yang ((can when) or (han shen)) ((chang ann) or (chang yun)) hong yu ;*".
