Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
su sach » so sach, vu sach
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
xa dung » xa dong, va dung, a dung
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, ly nang, v nang
ve cam » ve cham, ve cac, va cam

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 ve cam tuc ((xa dung) OR (xay dung)) tai ((cua triet) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang xa hoi. hieu ve cam tuc ((xa dung) OR (xay dung)) tai ((cua triet) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang xa hoi. hieu ve cam tuc ((xa dung) OR (xay dung)) tai ((cua triet) or (cuu tre))*".
