Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
dong bfo » dong bin, dong cao
bfo bias » quo bias
bias 4.3 » bias 1.3, bias 2.3, bias 4.6
4.3 when » 4.1 when, 9.3 when, 2.4.3 when
yang jin » yang jie, yang jun, ying jin
when so » when do, when co, when soft
so ging » so fing
yang xi » yang yi, yang jui

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: "dong bfo bias 4.3 when so ging ((((wang yang) OR (yang jin))) OR (((yang xi) OR (yang di)))) ;~".
• Adding a wildcard symbol may retrieve word variants: dong bfo bias 4.3 when so ging ((((wang yang) OR (yang jin))) OR (((yang xi) OR (yang di)))) ;*.
