Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
tu sach » thu sach, su sach, te sach
hieu ve » hieu va, hieu van
xuc van » duc van, luc van, vuc van
v nang » va nang, vu nang, van nang
ve cam » ve cham, ve cac, va cam
anh vi » hanh vi, anh ve, anh vu
anh va » hanh va

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 ((v nang) or (cam nang)) xa hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((v nang) OR (cam nang)) xa hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) su triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((v nang) or (cam nang)) xa hoi. hieu ve cam xuc van ((anh vi) OR (anh va)) su triet*".
