Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
cau theo » cau thi, cau tao
viec cac » vien cac, viec cua, viec lam
cau treo » cau tren, cau triet, cau trieu
danh vai » danh sai, danh va, doanh van
van danh » van doanh, van anh, van hanh
sach ky » sac ky, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
lo van » le van, vo van, so van
cac lo » cac lop, cac co, cac bo

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