cua tre » cua te, cua triet, dua tren
cac luc » cau luc, coc luc, cac nuoc
hieu va » hieu qua
xay hoi » xa hoi, tay hoi, cay phoi
sac ly » sac ky
luc va » duc va, tuc va, loc va
va xay » va xac
tu sac » tu sach, tu cac, tu san

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ly va xay hoi. ((hieu va) or (lieu va)) cac luc va hanh vai ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ly va xay hoi. ((hieu va) OR (lieu va)) cac luc va hanh vai ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ly va xay hoi. ((hieu va) or (lieu va)) cac luc va hanh vai ((cua tre) OR (cuu tre))*".
