Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
danh vai » danh sai, danh va, doanh van
van danh » van doanh, van anh, van hanh
vai cuu » vai cua
cach le » cach de, cach ben, cach lam
sach ky » sach y, sach ty, sach kem
nang xa » nang x, lang xa, nang ma
cuu tre » cua tre, cau tren, cau treo
cac le » cac he, mac le, bac le
sac ky » cac ky, sai ky

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