yang ying » yang yang, yang jing, huang ying
zhong tai » hong tan, hong hai, zhong zhi
ying can » ying chang, ying bank, ying yang
tan tan » tas tan, tang tang, tanz tanz
tin tan » tin can, wing tan
hong ng » hong kong, hong jong, hong 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 yang ying can become ((tan tan) OR (tin tan)) ((zhong tai) OR (((hong w) OR (hong ng)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ying can become ((tan tan) OR (tin tan)) ((zhong tai) or (((hong w) or (hong ng)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ying can become ((tan tan) OR (tin tan)) ((zhong tai) or (((hong w) or (hong ng)))) ;*.
