Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
one case » some case, one class, one phase
le bilan » les bilans, le blanc, le bien
bilan we » bilan de, milan we, bilan des
yan yuan » yan guan, fang yuan, nan yan
yang jui » yang xi, yang yi
case le » case l, case la, case like

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 le bilan we ((((yang yang) OR (yan yuan))) OR (yang jui)) ((yang judy) OR (yang di)) ;~.
• Adding a wildcard symbol may retrieve word variants: one case le bilan we ((((yang yang) or (yan yuan))) or (yang jui)) ((yang judy) or (yang di)) ;*.
