Perhaps you should try some spelling variations:
danh dien » dinh dien, danh kien, danh lien
muc tieu » qua tieu, duc tien, hoc tieu
cuc tieu » cac tieu, cach tieu, cung tieu
hieu va » lieu va
va danh » va dinh, va dan, va hanh
nang xa » nang x, lang xa, nang ma
te sach » toc sach
sach v » sach va, sach y, sach 2
soc va » hoc va, loc va, doc va
v nang » va nang, vu nang, van nang

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: te sach v nang xa hoi. ((hieu va) OR (hieu qua)) cham soc va danh dien ((cuc tieu) OR (muc tieu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang xa hoi. ((hieu va) OR (hieu qua)) cham soc va danh dien ((cuc tieu) or (muc tieu))~".
• Adding a wildcard symbol may retrieve word variants: te sach v nang xa hoi. ((hieu va) OR (hieu qua)) cham soc va danh dien ((cuc tieu) or (muc tieu))*.
