yin wang » yan wang, yin fang, yin hang
wang wei » zhang wei, wang zhi
wei chen » wei shen, frei chen, jui chen
yang jui » yang judy, yang yi
yang xi » yang yi
li yin » li ying, li lin, li jin

• If you are trying to use Boolean operators, they must be ALL CAPS: li yin wang wei chen ((((yang xi) OR (yang di))) OR (yang jui)) changes made ;*.
