Perhaps you should try some spelling variations:
guan chang » yuan chang, huang chang, han chang
yang cindy » yang mind
sang minh » kang minah, anh minh, song min
kann dan » kann man, kann das, mann dana
yan guan » gan guan, yan yuan, yang guang
tang min » chang min, yang mind, tang li
dan yan » dan yang, nan yan, wang yan
sar » sara, star, saur

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: kann dan yan guan chang ((yang cindy) OR (((tang min) OR (sang minh)))) kong sar ;~.
• Adding a wildcard symbol may retrieve word variants: kann dan yan guan chang ((yang cindy) or (((tang min) or (sang minh)))) kong sar ;*.
