Perhaps you should try some spelling variations:
changes threat » change threat, change threats, changes great
lang yanling » wang yangming, zhang yunling
1 changes » 2 changes, 3 changes, 4 changes
yang run » yang jun, yang yun, long run
tan ying » fan ying, ran ying, tan yang
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: ((lang yanling) OR (wang yanling)) ((yang run) OR (yang yi)) tan ying 1 changes threat ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yanling) OR (wang yanling)) ((yang run) or (yang yi)) tan ying 1 changes threat ;~".
• Adding a wildcard symbol may retrieve word variants: ((lang yanling) OR (wang yanling)) ((yang run) or (yang yi)) tan ying 1 changes threat ;*.
