yong yan » yang yang, dong yang, yong yoon
yu cheng » yu chen, _ cheng

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yong yan) OR (ying yang)) ((yulu chen) OR (yu cheng)) chan tung ((chun hui) OR (chun h)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yan) OR (ying yang)) ((yulu chen) or (yu cheng)) chan tung ((chun hui) or (chun h)) ;*".
