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