Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
chuan dan » chuan dato, chuan bang, chuan fa
sang minh » kang minah, anh minh, song min
minh dang » minh cong, mich dann
yang fan » yang dean, yang jin, yang jun
dan sang » dan yang, dan dana, dan qing
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: dong ((((yang fan) OR (yang yang))) OR (zhang fan)) chuan dan sang minh dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((((yang fan) OR (yang yang))) or (zhang fan)) chuan dan sang minh dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((((yang fan) OR (yang yang))) or (zhang fan)) chuan dan sang minh dang hai ;*.
