Perhaps you should try some spelling variations:
xiaodong yu » xiaodong yu's, xiaosong mu
xiaodong a » xiaojing a
yang cindy » yang mind
dang hari » dang hai
chia dan » chia lan, chia wen, shi dan
tang min » chang min, sang minh, yang mind
wang » wing, wan, lang

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: wang ((xiaodong a) OR (xiaodong yu)) chia dan ((tang min) OR (yang cindy)) dang hari ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((xiaodong a) OR (xiaodong yu)) chia dan ((tang min) or (yang cindy)) dang hari ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((xiaodong a) OR (xiaodong yu)) chia dan ((tang min) or (yang cindy)) dang hari ;*.
