yuan cheng » yuan chang, huang cheng, yu cheng
chi chang » chin chang, chia chiang, china chang
cheng yax » cheng han, cheng jay, cheng y
ying jin » yang jin, jing ji, yang jie
thao chi » hao chi, ho chi, giao chi

• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((((ying jin) OR (yang xi))) OR (yang yi)) thao chi chang yuan cheng yax ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((((ying jin) or (yang xi))) or (yang yi)) thao chi chang yuan cheng yax ;*.
