Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec lam » viec va
van hanh » van thanh, ban hanh, van anh
van danh » van doanh, van anh, van manh
vai cuu » vai cua
tu sach » thu sach, su sach, tu cach
nang xa » nang x, lang xa, nang ma
te sach » toc sach
cuu tre » cua tre, cau tren, cau treo
lam lo » nam lo, lam co, cam lo

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

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