Perhaps you should try some spelling variations:
change threat » change great
zhang yunling » zhang chunlin, zhang yuqin, zhang guoping
yang run » yang jun, yang yun, long run
tan ying » fan ying, ran ying, tan yang
1 change » 1 changes, 3 change, 2 change
yang yi » yang di, yang xi, yang jui
ying 1 » dying 1

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: ((zhang yunling) OR (wang yanling)) ((yang run) OR (yang yi)) tan ying 1 change threat ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((zhang yunling) OR (wang yanling)) ((yang run) or (yang yi)) tan ying 1 change threat ;~".
• Adding a wildcard symbol may retrieve word variants: ((zhang yunling) OR (wang yanling)) ((yang run) or (yang yi)) tan ying 1 change threat ;*.
