Perhaps you should try some spelling variations:
change your » changing your
chang you » change you, thing you, chang fwu
liang zhi » liang zhu, wang zhi, liang li
work some » works some, work home, work women
zhi best » i best, iii best
best run » best out
work sam » work s3p, work sex, work six

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: ((chang you) OR (change your)) liang zhi best run time ((work sam) OR (work some)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((chang you) or (change your)) liang zhi best run time ((work sam) OR (work some)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((chang you) or (change your)) liang zhi best run time ((work sam) OR (work some)) ;*.
