Perhaps you should try some spelling variations:
wang liang » wang yang
qiang sur » liang sun
hua best » a best
our best » your best, der best, our bit
spent 30 » spent _, sept 30, spent li
30 qiang » _ qiang, li qiang
hr best » der best, how best
dong » doing, long, done

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 sin) OR (wang liang)) ya ((hua best) OR (((our best) OR (hr best)))) spent 30 qiang sur ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (wang liang)) ya ((hua best) or (((our best) OR (hr best)))) spent 30 qiang sur ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (wang liang)) ya ((hua best) or (((our best) OR (hr best)))) spent 30 qiang sur ;*.
