Perhaps you should try some spelling variations:
life bilan » le bilan, life balance
case life » case like, phase life, late life
yan liang » yang liang, wang liang, you liang
one case » some case, one class, one phase
bilan de » bilan des, bilans de, bilanz des
yan yuan » yan guan, fang yuan, nan yan
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang xi, yang yi

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: one case life bilan de ((((yan liang) OR (yan yuan))) OR (yang jun)) ((yang jui) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case life bilan de ((((yan liang) or (yan yuan))) or (yang jun)) ((yang jui) or (yang di)) ;*.
