Perhaps you should try some spelling variations:
cao when » do when, so when, bay when
yang jie » yang jin, yang jui, yang yi
zhi dan » zhi duan, shi dan
dan cao » dan cao's, dong cao
when so » when do, when co, when soft
yang xi » yang yi, yang jui
so jin » so ein, song jin
wang » wing, wan, lang

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: wang zhi dan cao when so jin ((yang jie) OR (((yang di) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang zhi dan cao when so jin ((yang jie) or (((yang di) or (yang xi)))) ;*.
