Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
sach ty » sach y, sach tu, sach thu
danh vi » dinh vi, danh di, danh va
cam luc » cam xuc, cau luc
su sach » so sach, vu sach
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
luc va » duc va, tuc va, loc va

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 ty nang xa hoi. ((hieu ve) or (hieu qua)) cam luc va ((danh vi) OR (hanh vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty nang xa hoi. ((hieu ve) OR (hieu qua)) cam luc va ((danh vi) OR (hanh vi)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty nang xa hoi. ((hieu ve) or (hieu qua)) cam luc va ((danh vi) OR (hanh vi)) cua triet*".
