Perhaps you should try some spelling variations:
wing yan » wang yan, wing ian, wing tan
run cost » iran cost, can cost, run out
run cash » can cash, von cash, non cash
li qiang » li xiang, li keqiang, wei qiang
li gang » liu gang, ii gang, i gang
yan yi » yang yi, tan yi, yan zi
a cash » a case

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