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
yang shu » cong shu, tan shu, yang du
a close » a closer, a closed, _ close
do case » do cash, do care, two case
yan zi » yan zhi, yuan zi, ban zi

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