chang hua » chang ha, chang chuan, chang hsun
yang jie » yang di, yang jui, yang xi
yang jin » yang jun, ying jin, shang jin
hua tan » hua ban, huan t'an
yan jiu » pang jiu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang ying) OR (wang yang)) chang hua tan ((((yan jiu) or (yang jie))) or (yang jin)) cong shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang ying) OR (wang yang)) chang hua tan ((((yan jiu) OR (yang jie))) OR (yang jin)) cong shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) OR (wang yang)) chang hua tan ((((yan jiu) or (yang jie))) or (yang jin)) cong shu ;".
• Adding a wildcard symbol may retrieve word variants: ((wang ying) OR (wang yang)) chang hua tan ((((yan jiu) or (yang jie))) or (yang jin)) cong shu ;*.
