Perhaps you should try some spelling variations:
wang hong » wang hyoung, wang lihong, wang heyong
wang yong » wang yang, wang hyoung, wang yan
huang di » huang bin, huang lin, yang di
liang li » ling li, qiang li, liang wei
hong hai » shang hai, zhong tai, dang hai
wong yue » wang yue, hong yu
di rent » des rent, der rent, oil rent
lang li » ling li, tang li, wang 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 yong)) huang di rent ((lang li) OR (liang li)) ((hong hai) OR (wong yue)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang hong) or (wang yong)) huang di rent ((lang li) OR (liang li)) ((hong hai) or (wong yue)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang hong) or (wang yong)) huang di rent ((lang li) OR (liang li)) ((hong hai) or (wong yue)) ;*.
