Perhaps you should try some spelling variations:
life using » life during
using data » missing data
data don » data do, data den, data does
don chen » done when, goh chen, don ce
yang jui » yang di, yang xi
yang yun » yang jun, tang yun, yang yue
yang yi » yang di, yang xi

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: life using data don chen ((yang judy) OR (yang jui)) ((((yang yun) OR (wang yan))) OR (yang yi)) ;~.
• Adding a wildcard symbol may retrieve word variants: life using data don chen ((yang judy) or (yang jui)) ((((yang yun) or (wang yan))) or (yang yi)) ;*.
