Perhaps you should try some spelling variations:
yuan kang » yuan wang, yuan chang, chan kang
yan wang » yuan wang, yang yang, qian wang
hua rene » hua ren, juan rene
yang jin » yang jie, yang jun, ying jin
yang lin » wang lin, yang li, yang liang
tan hua » tuan hua, wang hua, tan chia
yan tin » yuan ting

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: ((yuan kang) OR (yan wang)) tan hua rene ((((yan tin) OR (yang jin))) OR (yang lin)) cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yuan kang) or (yan wang)) tan hua rene ((((yan tin) OR (yang jin))) or (yang lin)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((yuan kang) or (yan wang)) tan hua rene ((((yan tin) OR (yang jin))) or (yang lin)) cong shu ;*.
