hanh vai » hanh vi, hanh va, hanh tai
hieu va » lieu va, hieu qua

vai cua » dai cua, hai cua, lai cua
v nang » va nang, vu nang, van nang
y nang » ky nang, ly nang, may nang
tuc va » thuc va, truc va, tuc xa
luc va » duc va, loc va
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) OR (v nang)) x hoi. hieu va cham ((tuc va) or (luc va)) hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((y nang) OR (v nang)) x hoi. hieu va cham ((tuc va) OR (luc va)) hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((y nang) OR (v nang)) x hoi. hieu va cham ((tuc va) or (luc va)) hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: thu sach ((y nang) OR (v nang)) x hoi. hieu va cham ((tuc va) or (luc va)) hanh vai cua te*.
