danh vi » hanh vi, danh di, danh va
va cham » va chat, va tham
y nang » ky nang, ly nang, v nang
tuc va » thuc va, truc va, tuc xa
va dai » va dao, vi dai, va dau
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: thu sach y nang x hoi. hieu ((va dai) or (va cham)) tuc va ((danh vi) OR (dinh vi)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y nang x hoi. hieu ((va dai) OR (va cham)) tuc va ((danh vi) OR (dinh vi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y nang x hoi. hieu ((va dai) or (va cham)) tuc va ((danh vi) OR (dinh vi)) cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach y nang x hoi. hieu ((va dai) or (va cham)) tuc va ((danh vi) OR (dinh vi)) cua te*.
