Perhaps you should try some spelling variations:
ve triet » va trien
su triet » su viet, su tien
van hanh » van thanh, ban hanh, van anh
hanh ve » hanh vi, hanh va, hanh kem
xuc van » duc van, luc van, xuc ban
te sach » toc sach
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach y, sach 2
ve cam » ve cham, va cam, ve cai
v nang » va nang, vu nang, van nang
ve cac » va cac, vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach v nang xa hoi. hieu ((ve cam) or (ve cac)) xuc van hanh ve ((su triet) OR (ve triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang xa hoi. hieu ((ve cam) OR (ve cac)) xuc van hanh ve ((su triet) OR (ve triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. hieu ((ve cam) or (ve cac)) xuc van hanh ve ((su triet) OR (ve triet))".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. hieu ((ve cam) or (ve cac)) xuc van hanh ve ((su triet) OR (ve triet))*.
