Perhaps you should try some spelling variations:
during yang » during ianb
lang yuan » fang yuan, wang yuhan, meng yuan
can close » can lose, a close, can cause
can lost » can cost, can lose, can post
can cash » a cash
yang shu » cong shu, tan shu, yang du
yuan zi » yan zi, yuan li, yuan fei

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