Perhaps you should try some spelling variations:
juan meng » juan rene, jui meng, yuan ming
yang mind » yang cindy, sang minh, tang min
lang yan » wang yan, wang yang, zhang yan
yan minh » tuan minh, sang minh, yuan ming
yang jin » yang jie, yang jun, ying jin
cong van » congo can, duong van, cong sun
yi juan » y juan
yan yi » yang yi, tan yi, yan zi

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: lang yan yi juan meng ((((yan minh) OR (yang mind))) OR (yang jin)) cong van ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yi juan meng ((((yan minh) OR (yang mind))) or (yang jin)) cong van ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan yi juan meng ((((yan minh) OR (yang mind))) or (yang jin)) cong van ;*.
