Perhaps you should try some spelling variations:
wan hyoung » wang hyoung, man houng, min hyoung
irene yan » irene a
tin zhong » tin hong, bin zhang, ji zhong
zhong zhi » zhang zhi, hong ghi, zhong tai
yang hua » wang hua, yang hui, wang hui
yang jui » yang judy, yang di, yang xi
ying hua » ming hua, wang hua, ying zhu

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan hyoung ((((yang hua) OR (yang jui))) or (ying hua)) ((irene yan) or (ren yan)) tin zhong zhi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan hyoung ((((yang hua) OR (yang jui))) OR (ying hua)) ((irene yan) OR (ren yan)) tin zhong zhi ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan hyoung ((((yang hua) OR (yang jui))) or (ying hua)) ((irene yan) or (ren yan)) tin zhong zhi ;".
• Adding a wildcard symbol may retrieve word variants: wan hyoung ((((yang hua) OR (yang jui))) or (ying hua)) ((irene yan) or (ren yan)) tin zhong zhi ;*.
