Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
danh sai » danh bat, danh dau, hanh san
viec cac » vien cac, viec cua, viec lam
dung sai » dung tai, dung va, dung dat
cua tre » cuu tre, cua triet, dua tren
te sach » toc sach
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
bo van » vo van, so van, do van
cac bo » bac bo, cac co
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang xa hoi. nhieu viec cac bo van ((danh sai) OR (dung sai)) ((cua tre) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. nhieu viec cac bo van ((danh sai) OR (dung sai)) ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. nhieu viec cac bo van ((danh sai) OR (dung sai)) ((cua tre) or (cua te))*".
