Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
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
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, may nang
v nang » va nang, vu nang, van nang
cua lo » cua lao, cua loc, cua lop
lo van » le 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: su sach ((y nang) OR (v nang)) xa hoi. hieu viec cua lo van danh sai ((cuu tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((y nang) OR (v nang)) xa hoi. hieu viec cua lo van danh sai ((cuu tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((y nang) OR (v nang)) xa hoi. hieu viec cua lo van danh sai ((cuu tre) or (cua triet))*".
