yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi
ng y » ng _, g y, na y
wang » wing, wan, lang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (((yang xi) OR (yang jui))))ng y 2 current challenges yimin dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (((yang xi) OR (yang jui))))ng y 2 current challenges yimin dang hai ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (((yang xi) OR (yang jui))))ng y 2 current challenges yimin dang hai ;*.
