Perhaps you should try some spelling variations:
david mant » david ian, david malone, david martin
david dang » david ian, david ng
yang zili » yang dali, yang li
wan wang » wen wang, yan wang, wang yang
yang iii » klang iii, zwang iii, yang di
david ma » david a, david m, david ian
form i » form _, form a, reform i

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: wan wang ((yang iii) OR (yang zili)) form i ((david dang) OR (((david mant) OR (david ma)))) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan wang ((yang iii) or (yang zili)) form i ((david dang) or (((david mant) OR (david ma)))) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan wang ((yang iii) or (yang zili)) form i ((david dang) or (((david mant) OR (david ma)))) hai ;*.
