Perhaps you should try some spelling variations:
yang cindy » yang mind
dong gang » deng gang, dong yang, gong gang
cindy how » mind how, city how
gang yao » yang yao, wang yan, ganga ya
than bau » than bad, than a, than you
can data » can tata, dan data, fan data
how hai » how has, how ai, how hci

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 gang yao ((than bau) OR (can data)) yang cindy how hai ;~.
• Adding a wildcard symbol may retrieve word variants: dong gang yao ((than bau) or (can data)) yang cindy how hai ;*.
