Perhaps you should try some spelling variations:
ve triet » va trien, su triet
danh gia » dan gian
chat huu » pham huu
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu chat » va chat, ve chat, du chat
sach ly » sach lo, sach ty, sach hay
huu van » cuu van, huu han, luu van
hanh gi » hanh vi, hanh noi, hanh tai

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ly) or (sach y)) nang xa hoi. hieu vu chat huu van ((hanh gi) OR (danh gia)) ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ly) OR (sach y)) nang xa hoi. hieu vu chat huu van ((hanh gi) OR (danh gia)) ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ly) or (sach y)) nang xa hoi. hieu vu chat huu van ((hanh gi) OR (danh gia)) ve triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ly) or (sach y)) nang xa hoi. hieu vu chat huu van ((hanh gi) OR (danh gia)) ve triet*.
