yan clan » das clan, yan guan, yan yuan
hua gain » heat gain, run gain, hua ban
yang lin » yang jin, wang lin, yang li
yang jie » yang jin, yang di, yang jui
yan tan » tan tan, yan guan, yan wang
hai » hadi, haji, hari

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

• Performing a fuzzy search may retrieve terms with similar spellings: wai ((yan tan) OR (yan clan)) hua gain ((((wang yang) or (yang lin))) or (yang jie)) dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wai ((yan tan) OR (yan clan)) hua gain ((((wang yang) OR (yang lin))) OR (yang jie)) dang hai ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wai ((yan tan) OR (yan clan)) hua gain ((((wang yang) or (yang lin))) or (yang jie)) dang hai ;".
• Adding a wildcard symbol may retrieve word variants: wai ((yan tan) OR (yan clan)) hua gain ((((wang yang) or (yang lin))) or (yang jie)) dang hai ;*.
