Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
van thanh » ban thanh, van tuan
cau treo » cau theo, cau tren, cau triet
tu sach » thu sach, su sach, te sach
nang xa » nang x, lang xa, nang ma
vai cau » va cau, van cau, vai cac
y nang » ky nang, ly nang, v nang
cac lo » cac lop, cac bo, cac ho
cac co » cac cong

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