Perhaps you should try some spelling variations:
wang liang » wang yang
liang ka » liang dan, liang tan, jiang ke
than bau » than a, than you, than big
than bad » than a, than big, than law
can data » can tata, dan data, fan data
yang aid » yang anda, yang mind, yang di
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: wang liang ka ((((than bau) OR (than bad))) OR (can data)) yang aid how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ka ((((than bau) OR (than bad))) or (can data)) yang aid how hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ka ((((than bau) OR (than bad))) or (can data)) yang aid how hai ;*.
