yan zhang » yuan chang, bin zhang, hao zhang
han chang » huang chang, than change, can change

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan han) OR (((yan zhang) OR (han chang)))) health gain yang jin hyoung tan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan han) or (((yan zhang) OR (han chang)))) health gain yang jin hyoung tan ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan han) or (((yan zhang) OR (han chang)))) health gain yang jin hyoung tan ;*.
