Perhaps you should try some spelling variations:
first days » first day
one first » come first, one fast, one fits
days done » day one, has done, ways one
dong jung » hong jong, dong ping, dong yang
yang jin » yang jie, yang jun, ying jin
yang yun » yang jun, tang yun, yang yue
yang yi » yang xi, yang jui

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 first days done when ((((yang jin) OR (dong jung))) OR (yang yi)) ((yang yun) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one first days done when ((((yang jin) or (dong jung))) or (yang yi)) ((yang yun) or (yang di)) ;*.
