Perhaps you should try some spelling variations:
david mant » david ian, david ma, david malone
david dang » david ian, david ng
yang zili » yang dali
wan wang » wen wang, yan wang, wang yang
yang iii » klang iii, zwang iii, yang di
yang li » yang lin, yang di, yang xi
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) OR (yang li)))) form i ((david dang) OR (david mant)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan wang ((yang iii) or (((yang zili) or (yang li)))) form i ((david dang) OR (david mant)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: wan wang ((yang iii) or (((yang zili) or (yang li)))) form i ((david dang) OR (david mant)) hai ;*.
