Perhaps you should try some spelling variations:
sieu viet » su viet, dien viet, bien viet
hieu viec » nhieu viec, hieu ve, hieu hien
cau treo » cau theo, cau tren, cau triet
danh sai » dung sai, danh bat, danh dau
van danh » van doanh, van anh, van hanh
nang xa » nang x, lang xa, nang ma
cuu tre » cua tre, cau tren
tu sach » thu sach, su sach, te sach
y nang » ky nang, ly nang, v nang
cac co » cac cong
co van » cao 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: tu sach y nang xa hoi. ((hieu viec) OR (sieu viet)) cac co van danh sai ((cuu tre) or (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y nang xa hoi. ((hieu viec) OR (sieu viet)) cac co van danh sai ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y nang xa hoi. ((hieu viec) OR (sieu viet)) cac co van danh sai ((cuu tre) or (cau treo))*".
