Perhaps you should try some spelling variations:
yuan ting » yuan ming, huang ting, yuan kang
cong van » congo can, duong van, cong sun
van west » van soest, van het, van es
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
hong hai » shang hai, zhong tai, dang hai
yan tin » yang lin
wang » wing, wan, lang

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 yan cong van west ((((yan tin) OR (yuan ting))) OR (((yang jin) OR (yang jun)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan cong van west ((((yan tin) or (yuan ting))) or (((yang jin) OR (yang jun)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan cong van west ((((yan tin) or (yuan ting))) or (((yang jin) OR (yang jun)))) hong hai ;*.
