Perhaps you should try some spelling variations:
wang zaibang » wang liang, wang haiyan
wang lihong » wang liang, wang shiyong
tang yuan » fang yuan, tang yun, wang yuhan
yuan tan » huan t'an, yuan kang, yuan ting
tan yang » dan yang, tan ying, tan yong
yin yang » ying yang, yin fang, yin hang
yi yang » yi gang, yu yang, ying yang
dean » dewan, jean, den

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 zaibang) OR (wang lihong)) tang yuan tan yang ((yi yang) OR (yin yang)) dean ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang zaibang) or (wang lihong)) tang yuan tan yang ((yi yang) OR (yin yang)) dean ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang zaibang) or (wang lihong)) tang yuan tan yang ((yi yang) OR (yin yang)) dean ;*.
