Perhaps you should try some spelling variations:
qian yan » qian jun, qian yi
yang jin » yang jie, yang jun, ying jin
nan yan » nan ya, wang yan, dan yang
yi kang » xi kang, yi gang, jin kang
yi yang » yin yang, yi gang, ying yang
yu yang » du yang, yu fang, yu gang
cong » congo, long, hong

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((nan yan) or (qian yan)) yang jin ((((yi kang) OR (yi yang))) or (yu yang)) minh cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nan yan) OR (qian yan)) yang jin ((((yi kang) OR (yi yang))) OR (yu yang)) minh cong shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nan yan) or (qian yan)) yang jin ((((yi kang) OR (yi yang))) or (yu yang)) minh cong shu ;*".
