ve cai » va cai, ve cac, ve tai
v nang » va nang, vu nang, van nang
cua tu » cua tuc, cua su, cua cu
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: su sach v nang x hoi. hieu ((ve cai) or (va cam)) truc va ((hanh di) OR (hanh de)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang x hoi. hieu ((ve cai) OR (va cam)) truc va ((hanh di) OR (hanh de)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang x hoi. hieu ((ve cai) or (va cam)) truc va ((hanh di) OR (hanh de)) cua tu".
• Adding a wildcard symbol may retrieve word variants: su sach v nang x hoi. hieu ((ve cai) or (va cam)) truc va ((hanh di) OR (hanh de)) cua tu*.
