jeong shu » jeong su, cong shu
yan guan » gan guan, yan yuan, yang guang
chen han » cheng han, chen hao, chen tan

• If you are trying to use Boolean operators, they must be ALL CAPS: (lang OR wing) ((yan guan) OR (quan guan)) yi chen han min jeong shu ;~.
• Adding a wildcard symbol may retrieve word variants: (lang or wing) ((yan guan) or (quan guan)) yi chen han min jeong shu ;*.
