chang chen » chang ch'un, chang chuan, change when
zhang hari » shang hai, zhang han, zhang hui
zhang dai » zhang fan, zhang wei, zhang yan
yang li » yang lin, yang di, yang xi
chen e » chen _, chen wei

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) xiaodong chang chen e yang li ((zhang hari) OR (zhang dai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) xiaodong chang chen e yang li ((zhang hari) OR (zhang dai)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) xiaodong chang chen e yang li ((zhang hari) OR (zhang dai)) ;*.
