Perhaps you should try some spelling variations:
china data » china update, chinese data
wang kang » wang liang, wang yan, wang jing
wang yong » wang hyoung, wang yan, wang shiyong
wang yang » wang yan, wang liang, wang yanling
data yang » apa yang
yang jin » yang jie, yang jun, ying jin
jin dang » jin kang, jin chang, jing fang
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 kang) OR (wang yong))) OR (wang yang)) can china data yang jin dang hai ;~.
• Adding a wildcard symbol may retrieve word variants: ((((wang kang) or (wang yong))) or (wang yang)) can china data yang jin dang hai ;*.
