Perhaps you should try some spelling variations:
phase dong » phase during
one phase » die phase, one case, one page
yang yang » wang yang, wang yan
chang yun » chong yun, chang hsun, chae yun
dong bin » dong sin, dong di, dann bin
yang jie » yang jin, yang jui, yang xi
ying jin » yang jin, jing ji

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: one phase dong bin we ((((yang jie) OR (yang yang))) OR (ying jin)) ((chang yun) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one phase dong bin we ((((yang jie) or (yang yang))) or (ying jin)) ((chang yun) or (yang di)) ;*.
