Perhaps you should try some spelling variations:
minh zhong » minh cong, min hong
dong yang » dong hoang, wang yang, yang yang
sang minh » kang minah, anh minh, song min
zhong tai » hong tan, hong hai, zhong zhi
yang fan » zhang fan, yang dean, yang yang
than bau » than bad, than a, than you
can data » can tata, dan data, fan data

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 ((than bau) OR (can data)) sang minh zhong tai ;~.
• Adding a wildcard symbol may retrieve word variants: dong yang fan ((than bau) or (can data)) sang minh zhong tai ;*.
