Perhaps you should try some spelling variations:
sang minh » kang minah, anh minh, song min
wan yang » wang yang, dan yang, yang yang
tan yang » dan yang, tan ying, tan yong
ying jin » yang jin, jing ji, yang jie
yang xi » yang di, yang yi, yang jui
xi rene » i rene, ii rene, iii rene
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: ((wan yang) OR (tan yang)) yang xi rene ((sang minh) OR (ying jin)) dang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yang) OR (tan yang)) yang xi rene ((sang minh) or (ying jin)) dang hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yang) OR (tan yang)) yang xi rene ((sang minh) or (ying jin)) dang hai ;*.
