Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
van danh » van doanh, van anh, van hanh
danh sai » dung sai, danh bat, danh dau
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
cua loc » chua loc, cua hoc, cua lop
cuu tre » cau tren, cau treo
cua tre » cua te, cua triet, dua tren
y nang » ky nang, ly nang, v nang
cua lo » cua lao, cua lop, cua bo

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang xa hoi. hieu viec ((cua lo) OR (cua loc)) van danh sai ((cuu tre) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu viec ((cua lo) OR (cua loc)) van danh sai ((cuu tre) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu viec ((cua lo) OR (cua loc)) van danh sai ((cuu tre) or (cua tre))*".
