Perhaps you should try some spelling variations:
yang cindy » yang mind
dong yang » dong hoang, wang yang, yang yang
than daun » than daem, than data, than days
cindy how » mind how, city how
than bau » than bad, than a, than you
can data » can tata, dan data, fan data
yang yi » yang di, yang xi, yang jui
how ai » how aid, how ae, how am

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 yi ((((than daun) OR (than bau))) OR (can data)) yang cindy how ai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang yi ((((than daun) OR (than bau))) or (can data)) yang cindy how ai ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang yi ((((than daun) OR (than bau))) or (can data)) yang cindy how ai ;*.
