Perhaps you should try some spelling variations:
dinh hoi » dinh moi, dinh toi, dinh hoa
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
hoi cua » hoi chuc
ve cac » va cac, vien cac
xuc va » duc va, luc va, xac va
tuc va » thuc va, truc va, tuc xa
cua te » cua tu

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: su sach ty nang xa hoi. hieu ve cac ((xuc va) OR (tuc va)) dinh hoi cua te~.
• Adding a wildcard symbol may retrieve word variants: su sach ty nang xa hoi. hieu ve cac ((xuc va) or (tuc va)) dinh hoi cua te*.
