Perhaps you should try some spelling variations:
wang hong » wang yong, wang hyoung, wang lihong
wang yang » wang liang, wang yanling
shang kai » shang hai
rent tan » rent a
yang xi » yang di, yang yi, yang jui
xi rent » oil rent
hong yu » wong yue
tan li » tang li, tian li, gan li

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 hong) OR (((wang yang) OR (wang yan)))) yang xi rent tan li ((shang kai) OR (hong yu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang hong) or (((wang yang) OR (wang yan)))) yang xi rent tan li ((shang kai) or (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang hong) or (((wang yang) OR (wang yan)))) yang xi rent tan li ((shang kai) or (hong yu)) ;*.
