cua tre » cua te, cuu tre, dua tren
tu sach » thu sach, su sach, te sach
sach ky » sac ky, sach y, sach ty
tu cham » toc cham, thi cham
hieu tu » chieu tu, hieu tuc, hien tu
nang ma » tang ma, sang ma, nang cao
ma hoi » mai hoi, xa hoi, ma hoa
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang ma hoi. hieu tu cham ((xuc va) or (thuc vat)) hanh lam ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang ma hoi. hieu tu cham ((xuc va) OR (thuc vat)) hanh lam ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang ma hoi. hieu tu cham ((xuc va) or (thuc vat)) hanh lam ((cua tre) OR (cua triet))*".
