Perhaps you should try some spelling variations:
wang yihan » wang yidan, wang yuhan, wang yan
yihan guan » yan guan
yang mind » yang cindy, sang minh, tang min
guan jui » guan li, ruan ji
jui chen » yi chen
yang jin » yang jie, yang jun, ying jin
how shiu » how shih, how six, how she

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yihan guan jui chen ((yang mind) OR (yang jin)) how shiu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yihan guan jui chen ((yang mind) OR (yang jin)) how shiu ;*.
