Perhaps you should try some spelling variations:
thuat sach » thuat lanh, thuat san
su triet » su viet, su tien, ve triet
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
danh va » doanh va, hanh va, dan va
nam tu » nam thuc
anh va » hanh va

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

• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sach ky nang xa hoi. hieu ve ((nam tu) OR (nam thu)) va ((danh va) OR (anh va)) su triet~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sach ky nang xa hoi. hieu ve ((nam tu) or (nam thu)) va ((danh va) OR (anh va)) su triet~".
• Adding a wildcard symbol may retrieve word variants: thuat sach ky nang xa hoi. hieu ve ((nam tu) or (nam thu)) va ((danh va) OR (anh va)) su triet*.
