quan guan » gan guan, quan guo
gang sung » gang und, gang gong, hung sung
yan guan » gan guan, yan yuan, yang guang
run hsin » run gain, run pain

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wing OR lang) ((yan guan) OR (quan guan)) ((run hsin) OR (wen hsin)) huang gang sung min ;~.
• Adding a wildcard symbol may retrieve word variants: (wing or lang) ((yan guan) or (quan guan)) ((run hsin) or (wen hsin)) huang gang sung min ;*.
