yan guan » gan guan, yan yuan, yang guang
yan tan » tan tan, yan clan, yan wang
hong yu » wong yue
a hong » _ hong, kia hong, tan hong

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: (wang OR wing) ((yan tan) OR (yan guan)) hsu ((chin chang) OR (china chang)) a hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yan tan) OR (yan guan)) hsu ((chin chang) or (china chang)) a hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yan tan) OR (yan guan)) hsu ((chin chang) or (china chang)) a hong yu ;*.
