Perhaps you should try some spelling variations:
hieu vien » hieu hien, hieu viec, thieu nien
ve triet » va trien
su triet » su viet, su tien
vien cac » vien bach, vien dai, vien da
qua ban » cua ban, qua quan
hanh ve » hanh vi, hanh va, hanh kem
su sach » so sach, vu sach
dua ban » dia ban, cua ban, mua ban
sach v » sach va, sach y, sach 2
v nang » va nang, vu nang, van nang
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 vien cac ((dua ban) or (qua ban)) hanh ve ((su triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach v nang x hoi. hieu vien cac ((dua ban) OR (qua ban)) hanh ve ((su triet) OR (ve triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach v nang x hoi. hieu vien cac ((dua ban) or (qua ban)) hanh ve ((su triet) OR (ve triet))*".
