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