Perhaps you should try some spelling variations:
than daun » than bau, than daem, than data
than deep » can deep, than daem
sang minh » kang minah, anh minh, song min
minh hong » minh cong, min hong, linh hoang
yang fan » zhang fan, yang dean, yang yang
hong hai » shang hai, zhong tai, dang hai
yang ka » yang yao

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 ka) OR (yang fan)) ((than daun) OR (than deep)) sang minh hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang ka) OR (yang fan)) ((than daun) or (than deep)) sang minh hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: dong ((yang ka) OR (yang fan)) ((than daun) or (than deep)) sang minh hong hai ;*.
