Perhaps you should try some spelling variations:
qian yan » qian jun, qian yi
asia wen » asia why, chia wen
wen yong » wang yong, chen yong, zhen yong
yong lin » yang lin, song lina, yong kim
hong hai » shang hai, zhong tai, dang hai
nan yan » nan ya, dan yang, nana yaa
zong he » zheng he

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