Perhaps you should try some spelling variations:
chen yang » chen rong
shang kai » shang hai
wang nan » wang yan, wang ban, wang dan
chen tan » chen tain, chen jian, chen wang
chia lan » china land, china law, chia wen
yong lin » yang lin, song lina, yong kim
nan yan » nan ya, wang yan, qian yan

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 nan yan ((((chen tan) OR (chen yang))) OR (chia lan)) yong lin ((dang hai) OR (shang kai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang nan yan ((((chen tan) OR (chen yang))) or (chia lan)) yong lin ((dang hai) or (shang kai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang nan yan ((((chen tan) OR (chen yang))) or (chia lan)) yong lin ((dang hai) or (shang kai)) ;*.
