Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
sach nuoc » sach duoc, cac nuoc, bach tuoc
hieu van » hieu va, thien van, lieu va
dung doi » huong doi, dung tai, dung co
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
va dung » van dung, va duong, vat dung
cua tre » cuu tre, cua triet, dua tren
y nang » ky nang, ly nang, v nang
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 y nang xa hoi. ((hieu viec) OR (hieu van)) sach nuoc va dung doi ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. ((hieu viec) or (hieu van)) sach nuoc va dung doi ((cua tre) OR (cua te))~".
• Adding a wildcard symbol may retrieve word variants: su sach y nang xa hoi. ((hieu viec) or (hieu van)) sach nuoc va dung doi ((cua tre) OR (cua te))*.
