Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
doanh van » doan van, doanh va, doanh ban
viec cac » vien cac, viec cua, viec lam
danh vai » danh sai, danh va, dang van
te sach » toc sach
cuu tre » cua tre, cau tren, cau treo
sach ky » sac ky, sach y, sach ty
nang xa » nang x, lang xa, nang ma
su van » tu van, vu van
lo van » le van, vo van, so van

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 ((lo van) or (su van)) ((danh vai) OR (doanh van)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang xa hoi. nhieu viec cac ((lo van) OR (su van)) ((danh vai) OR (doanh van)) cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang xa hoi. nhieu viec cac ((lo van) or (su van)) ((danh vai) OR (doanh van)) cuu tre*".
