Perhaps you should try some spelling variations:
wang liang » wang yang
liang ka » liang dan, liang tan, jiang ke
than bau » than bad, than a, than you
can data » can tata, dan data, chain data
fan data » dan data, loan data, main data
yang jin » yang jie, yang jun, ying jin
jin how » john how
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 (((can data) OR (fan data)))) yang jin how hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ka ((than bau) or (((can data) OR (fan data)))) yang jin how hai ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ka ((than bau) or (((can data) OR (fan data)))) yang jin how hai ;*.
