Perhaps you should try some spelling variations:
china wen » chia wen, china won, ching wen
wen yong » wang yong, chen yong, zhen yong
yong lin » yang lin, song lina, yong kim
zong hai » dang hai, long han, zong he
hong hai » shang hai, zhong tai, dang hai
ban can » bank can, banks can
man can » man han, woman can, man kann

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 ((ban can) OR (man can)) china wen yong lin ((zong hai) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((ban can) OR (man can)) china wen yong lin ((zong hai) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((ban can) OR (man can)) china wen yong lin ((zong hai) or (hong hai)) ;*.
