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 cost » can costa, can lost, can post
run cash » can cash, von cash, non 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 cost) OR (can close))) OR (run cash)) being during yang shu ;~.
• Adding a wildcard symbol may retrieve word variants: lang yuan zi ((((can cost) or (can close))) or (run cash)) being during yang shu ;*.
