Perhaps you should try some spelling variations:
wang dan » wang yan, wang yidan, wang yang
wang ban » wang yan, wang yang, bang bang
hua rene » hua ren, juan rene
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
tan hua » tuan hua, wang hua, tan chia
yan jiu » yang jie, pang jiu

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: "((wang dan) OR (wang ban)) tan hua rene ((((yan jiu) OR (yang jin))) OR (yang jun)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) OR (wang ban)) tan hua rene ((((yan jiu) OR (yang jin))) OR (yang jun)) cong shu ;*.
