Perhaps you should try some spelling variations:
life using » life during
using dhm » using dem, using ddms, using dhcp
time when » time what
dhm time » das time, den time, pwm time
yong jin » yang jin, ying jin, song jin
yang jui » yang judy, yang di, yang xi
yang yun » yang jun, tang yun, yang yue

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 dhm time when ((yong jin) OR (yang jui)) ((yang yun) OR (yang (judy OR july))) ;~.
• Adding a wildcard symbol may retrieve word variants: life using dhm time when ((yong jin) or (yang jui)) ((yang yun) or (yang (judy or july))) ;*.
