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

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