Perhaps you should try some spelling variations:
during yang » during ianb
can boost » a boost, can best
lang yan » wang yan, wang yang, zhang yan
can lose » can close, can lost, can losers
can cash » a cash
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 boost) OR (can lose))) OR (can cash)) being during yang shu ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan zhi ((((can boost) or (can lose))) or (can cash)) being during yang shu ;*.
