Perhaps you should try some spelling variations:
savings group » savings groups
hua yang » hui yang, huang yang, hua jiang
di costo » del costo, di cristo, da costa
yi cost » ii cost, die cost
group a » group _, group 2
h yang » _ yang, hui yang
a shu » _ shu
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((hua yang) or (h yang)) ((yi cost) OR (di costo)) savings group a shu ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((hua yang) OR (h yang)) ((yi cost) OR (di costo)) savings group a shu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((hua yang) or (h yang)) ((yi cost) OR (di costo)) savings group a shu ;*".
