yi cheng » yi chen, yu cheng, xi cheng
nan yan » nan ya, wang yan, qian yan

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