Perhaps you should try some spelling variations:
can close » can lose, a close, can cause
wing yan » wang yan, wing ian, wing tan
von cash » von carl, do cash, von cand
can cash » a cash
li cong » li song, jiu cong
li rong » yi rong, li song, shi rong
yan yi » yang yi, tan yi, yan zi

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: wing yan yi ((can close) OR (((von cash) OR (can cash)))) sharing ((li cong) OR (li rong)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan yi ((can close) or (((von cash) OR (can cash)))) sharing ((li cong) or (li rong)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan yi ((can close) or (((von cash) OR (can cash)))) sharing ((li cong) or (li rong)) shu ;*.
