chang hong » change hong, zhang hong, change long
wang yang » wang yan, wang liang, wang yanling
chen chin » chin chin, chen chih, chen chuan
chen chiu » chen chih, cheng chu, chen zhi
hong jong » hong kong
jong yu » hong yu, rong yu, wong yue

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 ((wang yang) OR (yang liang)) ((chen chin) OR (chen chiu)) chang hong jong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang yang) or (yang liang)) ((chen chin) OR (chen chiu)) chang hong jong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wang yang) or (yang liang)) ((chen chin) OR (chen chiu)) chang hong jong yu ;*.
