Perhaps you should try some spelling variations:
tested using » test using, tests using, testing using
liang jing » wang jing, bian jing, huang jing
liang ying » liang liying, huang ying, zhang ying
kong sara » kong sar
i tested » _ tested, a nested, i test
using a » using _
a kong » w kong, tan kong, nan kong

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 jing) OR (liang ying)) i tested using a kong sara ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((liang jing) or (liang ying)) i tested using a kong sara ;*.
