Perhaps you should try some spelling variations:
costs creating » outs creating, charts creating, crises creating
costs ratings » costs savings, cost savings, bonds ratings
liang liying » jiang liping, liang lilin, liang ying
risk wrong » risk among, risk along
wang yang » wang yan, wang liang, wang yanling
wrong who » wrong why, wrong what, wrong when

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((wang yang) or (liang liying)) user ((costs ratings) OR (costs creating)) risk wrong who ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((wang yang) OR (liang liying)) user ((costs ratings) OR (costs creating)) risk wrong who ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang yang) or (liang liying)) user ((costs ratings) OR (costs creating)) risk wrong who ;*".
