ying jin » yang jin, yang jie
tan yan » tan yang, nan yan, tan tan

• If you are trying to use Boolean operators, they must be ALL CAPS: tan yan zhang jian chen ((((yang xi) OR (((ying jin) OR (jing ji))))) OR (yang di)) changes made ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan yan zhang jian chen ((((yang xi) or (((ying jin) OR (jing ji))))) or (yang di)) changes made ;*".
