Perhaps you should try some spelling variations:
when gong » when songs, when good, when goal
doing un » doing und, doing our, doing von
cao when » do when, so when, bay when
gong min » jong min, song min, gong meng
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
dan cao » dan cao's, dong cao
yang xi » yang yi, 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: doing un dan cao when gong min ((((yang jin) OR (yang jun))) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing un dan cao when gong min ((((yang jin) or (yang jun))) or (((yang di) or (yang xi)))) ;*.
