Perhaps you should try some spelling variations:
zhang ming » zhang xin
yang yang » wang yang, wang yan
test ying » test using, test playing
chang min » chang mae, chan ming, chang ann
dong nan » dong yang, dong sin, dong bin
ying jin » yang jin, jing ji, yang jie
lang 2 » lang 3, lang _, lang a
2 test » 3.2 test

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 nan) OR (yang yang)) lang 2 test ying jin ((chang min) OR (zhang ming)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (yang yang)) lang 2 test ying jin ((chang min) OR (zhang ming)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (yang yang)) lang 2 test ying jin ((chang min) OR (zhang ming)) ;*.
