Perhaps you should try some spelling variations:
during yang » during ianb
non cause » non use, can cause, en cause
lang yan » wang yan, wang yang, zhang yan
can lost » can cost, can lose, can post
yang shu » cong shu, tan shu, yang du
yan zhi » yan zi, wang zhi
a close » a closer, a closed, _ close

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: lang yan zhi ((((can lost) OR (a close))) OR (non cause)) being during yang shu ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan zhi ((((can lost) or (a close))) or (non cause)) being during yang shu ;*.
