Perhaps you should try some spelling variations:
donor when » done when
one first » come first, one fast, one fits
aid donor » aid donors, a donor
dong ping » dong sin, dong bin, dong jung
yang jie » yang jin, yang yi, yang jun
yang jui » yang judy, yang yi
yang xi » yang yi

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: one first aid donor when ((((yang jie) or (dong ping))) or (yang xi)) ((yang jui) or (yang di)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: one first aid donor when ((((yang jie) OR (dong ping))) OR (yang xi)) ((yang jui) OR (yang di)) ;*.
