Perhaps you should try some spelling variations:
zwang iii » zugang iii, klang iii
yang dali » yang di, yang all, yang li
bang dai » zhang dai
david ng » david g, david n, david a
i david » 2 david, die david, iii david
form i » form _, form a, reform i
ng hai » dang hai, hong hai
wang » wing, wan, lang
zwang » zwing, zwan, zlang

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 yan ((zwang iii) OR (((yang dali) OR (bang dai)))) form i david ng hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((zwang iii) or (((yang dali) OR (bang dai)))) form i david ng hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((zwang iii) or (((yang dali) OR (bang dai)))) form i david ng hai ;*.
