chang chen » chang ch'un, chang chuan, change when
hong than » hong tan, long thanh, hong hai
eng hong » hong hong, kong hong, ong chong
tan eng » tan cheng, tan hong, tan kong
wang » wing, wan
hai » hadi, haji, hari

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 lang) xiaotong ((zhang chen) OR (chang chen)) tan eng hong ((hong than) OR (dang hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) xiaotong ((zhang chen) OR (chang chen)) tan eng hong ((hong than) or (dang hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) xiaotong ((zhang chen) OR (chang chen)) tan eng hong ((hong than) or (dang hai)) ;*.
